• JSON中JObject和JArray,JValue序列化(Linq)

    一、JObject和JArray序列化

    1.实例化JArray和JObject，然后序列化

    [csharp] view plain copy
     
    print?
    1. using System;  
    2. using System.Collections.Generic;  
    3. using System.Linq;  
    4. using System.Text;  
    5. using System.Data;  
    6. using GongHuiNewtonsoft.Json.Linq;  
    7.   
    8. namespace JSONDemo  
    9. {  
    10.     class Program  
    11.     {  
    12.         static void Main(string[] args)  
    13.         {  
    14.             JArray array = new JArray();  
    15.             array.Add("GongHui Linq");  
    16.             array.Add(new DateTime(2015, 12, 14));  
    17.   
    18.             JObject o = new JObject();  
    19.             o["myArray"] = array;  
    20.   
    21.             string json = o.ToString();  
    22.   
    23.             Console.WriteLine(json);  
    24.         }  
    25.     }  
    26. }  
    using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Data;
using GongHuiNewtonsoft.Json.Linq;

namespace JSONDemo
{
    class Program
    {
        static void Main(string[] args)
        {
            JArray array = new JArray();
            array.Add("GongHui Linq");
            array.Add(new DateTime(2015, 12, 14));

            JObject o = new JObject();
            o["myArray"] = array;

            string json = o.ToString();

            Console.WriteLine(json);
        }
    }
}


    2.运行结果

      

    二、JObject和JArray使用C#集合初始化语法序列化

    1.使用C#集合初始化语法,并序列化

    [csharp] view plain copy
     
    print?
    1. using System;  
    2. using System.Collections.Generic;  
    3. using System.Linq;  
    4. using System.Text;  
    5. using System.Data;  
    6. using GongHuiNewtonsoft.Json.Linq;  
    7.   
    8. namespace JSONDemo  
    9. {  
    10.     class Program  
    11.     {  
    12.         static void Main(string[] args)  
    13.         {  
    14.             JObject o = new JObject   
    15.             {  
    16.                 {"CPU","Intel"},  
    17.                 {"Memory",2048},  
    18.                 {  
    19.                     "Drives",new JArray  
    20.                     {  
    21.                         "DVD",  
    22.                         "U盘"  
    23.                     }  
    24.                 }  
    25.             };  
    26.   
    27.             Console.WriteLine(o.ToString());  
    28.         }  
    29.     }  
    30. }  
    using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Data;
using GongHuiNewtonsoft.Json.Linq;

namespace JSONDemo
{
    class Program
    {
        static void Main(string[] args)
        {
            JObject o = new JObject 
            {
                {"CPU","Intel"},
                {"Memory",2048},
                {
                    "Drives",new JArray
                    {
                        "DVD",
                        "U盘"
                    }
                }
            };

            Console.WriteLine(o.ToString());
        }
    }
}


    2.运行结果

    三、使用Linq创建JObject和JArray序列化

    1.创建一个Post对象，添加构造函数。

    [csharp] view plain copy
     
    print?
    1. using System;  
    2. using System.Collections.Generic;  
    3. using System.Linq;  
    4. using System.Text;  
    5.   
    6. namespace JSONDemo  
    7. {  
    8.     public class Post  
    9.     {  
    10.         public string Title { get; set; }  
    11.         public string Description { get; set; }  
    12.         public string Link { get; set; }  
    13.         public IList<string> Categories { get; set; }  
    14.   
    15.         public Post()  
    16.         {  
    17.             Categories = new List<string>();  
    18.         }  
    19.     }  
    20. }  
    using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace JSONDemo
{
    public class Post
    {
        public string Title { get; set; }
        public string Description { get; set; }
        public string Link { get; set; }
        public IList<string> Categories { get; set; }

        public Post()
        {
            Categories = new List<string>();
        }
    }
}


    2.实例化Post，然后声明一个对象列表。

    [csharp] view plain copy
     
    print?
    1. using System;  
    2. using System.Collections.Generic;  
    3. using System.Linq;  
    4. using System.Text;  
    5. using System.Data;  
    6. using GongHuiNewtonsoft.Json.Linq;  
    7.   
    8. namespace JSONDemo  
    9. {  
    10.     class Program  
    11.     {  
    12.         static void Main(string[] args)  
    13.         {  
    14.             Post p1=new Post();  
    15.             p1.Title="张五";  
    16.             p1.Description="张五的五一";  
    17.             p1.Link="http://www.zhuangwu.com";  
    18.             p1.Categories.Add("天地不仁");  
    19.   
    20.             IList<Post> posts=new List<Post>();  
    21.             posts.Add(p1);  
    22.   
    23.             JObject o = new JObject(  
    24.                 new JProperty("channel",  
    25.                     new JObject(  
    26.                         new JProperty("title","龚辉"),  
    27.                         new JProperty("link","http://blog.csdn.net/lovegonghui/article/details/50293629"),  
    28.                         new JProperty("description","龚辉的博客"),  
    29.                         new JProperty("item",  
    30.                             new JArray(  
    31.                                 from p in posts  
    32.                                 orderby p.Title       
    33.                                 select new JObject(  
    34.                                     new JProperty("title",p.Title),  
    35.                                     new JProperty("description",p.Description),  
    36.                                     new JProperty("link",p.Link),  
    37.                                     new JProperty("categories",  
    38.                                         new JArray(  
    39.                                             from c in p.Categories  
    40.                                             select new JValue(c)))  
    41.                                         )  
    42.                                 )  
    43.                             )  
    44.                     )  
    45.                 )      
    46.             );  
    47.             Console.WriteLine(o.ToString());  
    48.         }  
    49.     }  
    50. }  
    using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Data;
using GongHuiNewtonsoft.Json.Linq;

namespace JSONDemo
{
    class Program
    {
        static void Main(string[] args)
        {
            Post p1=new Post();
            p1.Title="张五";
            p1.Description="张五的五一";
            p1.Link="http://www.zhuangwu.com";
            p1.Categories.Add("天地不仁");

            IList<Post> posts=new List<Post>();
            posts.Add(p1);

            JObject o = new JObject(
                new JProperty("channel",
                    new JObject(
                        new JProperty("title","龚辉"),
                        new JProperty("link","http://blog.csdn.net/lovegonghui/article/details/50293629"),
                        new JProperty("description","龚辉的博客"),
                        new JProperty("item",
                            new JArray(
                                from p in posts
                                orderby p.Title     
                                select new JObject(
                                    new JProperty("title",p.Title),
                                    new JProperty("description",p.Description),
                                    new JProperty("link",p.Link),
                                    new JProperty("categories",
                                        new JArray(
                                            from c in p.Categories
                                            select new JValue(c)))
                                        )
                                )
                            )
                    )
                )    
            );
            Console.WriteLine(o.ToString());
        }
    }
}

    3.运行的结果

    四、使用C#的dynamic序列化

    1.创建一个对象Address.

    [csharp] view plain copy
     
    print?
    1. using System;  
    2. using System.Collections.Generic;  
    3. using System.Linq;  
    4. using System.Text;  
    5. using System.ComponentModel;  
    6.   
    7. namespace JSONDemo  
    8. {  
    9.     public class Address  
    10.     {  
    11.         public string Province { get; set; }  
    12.         public string City { get; set; }  
    13.         public string County { get; set; }  
    14.         public IList<string> Villages { get; set; }          
    15.     }  
    16. }  
    using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ComponentModel;

namespace JSONDemo
{
    public class Address
    {
        public string Province { get; set; }
        public string City { get; set; }
        public string County { get; set; }
        public IList<string> Villages { get; set; }        
    }
}


    2.序列化

    [csharp] view plain copy
     
    print?
    1. using System;  
    2. using System.Collections.Generic;  
    3. using System.Linq;  
    4. using System.Text;  
    5. using System.Data;  
    6. using GongHuiNewtonsoft.Json.Linq;  
    7.   
    8. namespace JSONDemo  
    9. {  
    10.     class Program  
    11.     {  
    12.         static void Main(string[] args)  
    13.         {             
    14.   
    15.             dynamic address = new JObject();  
    16.             address.Province = "GuangDong";  
    17.             address.City = "GuangZhou";  
    18.             address.County = "PanYu";  
    19.             address.Villages = new JArray("大龙村", "小龙村");  
    20.   
    21.             Console.WriteLine(address.ToString());  
    22.         }  
    23.     }  
    24. }  
    using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Data;
using GongHuiNewtonsoft.Json.Linq;

namespace JSONDemo
{
    class Program
    {
        static void Main(string[] args)
        {           

            dynamic address = new JObject();
            address.Province = "GuangDong";
            address.City = "GuangZhou";
            address.County = "PanYu";
            address.Villages = new JArray("大龙村", "小龙村");

            Console.WriteLine(address.ToString());
        }
    }
}


    3.运行的结果

    五、使用JTokenWriter序列化

    1.首先使用JTokenWriter写入属性与值，数组。

    [csharp] view plain copy
     
    print?
    1. using System;  
    2. using System.Collections.Generic;  
    3. using System.Linq;  
    4. using System.Text;  
    5. using System.Data;  
    6. using GongHuiNewtonsoft.Json.Linq;  
    7.   
    8. namespace JSONDemo  
    9. {  
    10.     class Program  
    11.     {  
    12.         static void Main(string[] args)  
    13.         {  
    14.             JTokenWriter writer = new JTokenWriter();  
    15.             writer.WriteStartObject();  
    16.             writer.WritePropertyName("Title");  
    17.             writer.WriteValue("薄谷开来案???");  
    18.   
    19.             writer.WritePropertyName("Detail");     
    20.           
    21.             writer.WriteStartArray();  
    22.             writer.WriteValue("Yes");  
    23.             writer.WriteValue("No");  
    24.             writer.WriteValue("Unknown");  
    25.             writer.WriteEndArray();  
    26.   
    27.             writer.WriteEndObject();  
    28.   
    29.             JObject o = (JObject)writer.Token;  
    30.             Console.WriteLine(o.ToString());  
    31.         }  
    32.     }  
    33. }  
    using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Data;
using GongHuiNewtonsoft.Json.Linq;

namespace JSONDemo
{
    class Program
    {
        static void Main(string[] args)
        {
            JTokenWriter writer = new JTokenWriter();
            writer.WriteStartObject();
            writer.WritePropertyName("Title");
            writer.WriteValue("薄谷开来案???");

            writer.WritePropertyName("Detail");   
        
            writer.WriteStartArray();
            writer.WriteValue("Yes");
            writer.WriteValue("No");
            writer.WriteValue("Unknown");
            writer.WriteEndArray();

            writer.WriteEndObject();

            JObject o = (JObject)writer.Token;
            Console.WriteLine(o.ToString());
        }
    }
}


    2.运行的结果

      

    六、使用JToken.FromObject(object)把.NET值转换成JSON中Linq序列化

    1.先创建一个Address对象.

    [csharp] view plain copy
     
    print?
    1. using System;  
    2. using System.Collections.Generic;  
    3. using System.Linq;  
    4. using System.Text;  
    5. using System.ComponentModel;  
    6.   
    7. namespace JSONDemo  
    8. {  
    9.     public class Address  
    10.     {  
    11.         public string Province { get; set; }  
    12.         public string City { get; set; }  
    13.         public string County { get; set; }  
    14.         public IList<string> Villages { get; set; }          
    15.     }  
    16. }  
    using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ComponentModel;

namespace JSONDemo
{
    public class Address
    {
        public string Province { get; set; }
        public string City { get; set; }
        public string County { get; set; }
        public IList<string> Villages { get; set; }        
    }
}


    2.序列化操作

    [csharp] view plain copy
     
    print?
    1. using System;  
    2. using System.Collections.Generic;  
    3. using System.Linq;  
    4. using System.Text;  
    5. using System.Data;  
    6. using GongHuiNewtonsoft.Json.Linq;  
    7.   
    8. namespace JSONDemo  
    9. {  
    10.     class Program  
    11.     {  
    12.         static void Main(string[] args)  
    13.         {  
    14.             JValue i = (JValue)JToken.FromObject(123);  
    15.             Console.WriteLine(i.Type);  
    16.             Console.WriteLine(i.ToString());  
    17.   
    18.             JValue s = (JValue)JToken.FromObject("GongHui");  
    19.             Console.WriteLine(s.Type);  
    20.             Console.WriteLine(s.ToString());  
    21.   
    22.             Address address = new Address  
    23.             {  
    24.                 City = "GuangZhou",  
    25.                 Province = "GuangDong",  
    26.                 County = "ShiQiao",  
    27.                 Villages = new List<string>  
    28.                 {  
    29.                     "维和",  
    30.                     "防稳"  
    31.                 }  
    32.             };  
    33.   
    34.             JObject o = (JObject)JToken.FromObject(address);  
    35.             Console.WriteLine(o.ToString());  
    36.         }  
    37.     }  
    38. }  
    using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Data;
using GongHuiNewtonsoft.Json.Linq;

namespace JSONDemo
{
    class Program
    {
        static void Main(string[] args)
        {
            JValue i = (JValue)JToken.FromObject(123);
            Console.WriteLine(i.Type);
            Console.WriteLine(i.ToString());

            JValue s = (JValue)JToken.FromObject("GongHui");
            Console.WriteLine(s.Type);
            Console.WriteLine(s.ToString());

            Address address = new Address
            {
                City = "GuangZhou",
                Province = "GuangDong",
                County = "ShiQiao",
                Villages = new List<string>
                {
                    "维和",
                    "防稳"
                }
            };

            JObject o = (JObject)JToken.FromObject(address);
            Console.WriteLine(o.ToString());
        }
    }
}


    3.运行结果

    七、匿名类型创建一个JObject序列化

    1.先创建一个Post对象

    [csharp] view plain copy
     
    print?
    1. using System;  
    2. using System.Collections.Generic;  
    3. using System.Linq;  
    4. using System.Text;  
    5.   
    6. namespace JSONDemo  
    7. {  
    8.     public class Post  
    9.     {  
    10.         public string Title { get; set; }  
    11.         public string Description { get; set; }  
    12.         public string Link { get; set; }  
    13.         public IList<string> Categories { get; set; }         
    14.     }  
    15. }  
    using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace JSONDemo
{
    public class Post
    {
        public string Title { get; set; }
        public string Description { get; set; }
        public string Link { get; set; }
        public IList<string> Categories { get; set; }       
    }
}


    2.实例化对象Post,然后使用JObject.FromObject(object)创建一个匿名类型对象channel

    [csharp] view plain copy
     
    print?
    1. using System;  
    2. using System.Collections.Generic;  
    3. using System.Linq;  
    4. using System.Text;  
    5. using System.Data;  
    6. using GongHuiNewtonsoft.Json.Linq;  
    7.   
    8. namespace JSONDemo  
    9. {  
    10.     class Program  
    11.     {  
    12.         static void Main(string[] args)  
    13.         {  
    14.             List<Post> posts = new List<Post>  
    15.             {  
    16.                 new Post  
    17.                 {  
    18.                     Title="匿名类型",  
    19.                     Description="匿名类型创建一个JObject",  
    20.                     Link="http://write.blog.csdn.net/postedit/50293629",  
    21.                     Categories=new List<string>  
    22.                     {  
    23.                         "JObject",  
    24.                         "匿名类型"  
    25.                     }  
    26.                 }  
    27.             };  
    28.   
    29.             JObject o = JObject.FromObject(new  
    30.             {  
    31.                 channel = new  
    32.                 {  
    33.                     title = "Linq的测试",  
    34.                     link = "http://www.microsoft/Linq.com",  
    35.                     description = "这是JOSN在Linq在的测试",  
    36.                     item =  
    37.                      from p in posts  
    38.                      orderby p.Title  
    39.                      select new   
    40.                      {  
    41.                          title=p.Title,  
    42.                          link=p.Link,  
    43.                          description=p.Description,  
    44.                          categories=p.Categories  
    45.                      }  
    46.                 }  
    47.             }  
    48.             );  
    49.   
    50.             Console.WriteLine(o.ToString());  
    51.         }  
    52.     }  
    53. }  
    using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Data;
using GongHuiNewtonsoft.Json.Linq;

namespace JSONDemo
{
    class Program
    {
        static void Main(string[] args)
        {
            List<Post> posts = new List<Post>
            {
                new Post
                {
                    Title="匿名类型",
                    Description="匿名类型创建一个JObject",
                    Link="http://write.blog.csdn.net/postedit/50293629",
                    Categories=new List<string>
                    {
                        "JObject",
                        "匿名类型"
                    }
                }
            };

            JObject o = JObject.FromObject(new
            {
                channel = new
                {
                    title = "Linq的测试",
                    link = "http://www.microsoft/Linq.com",
                    description = "这是JOSN在Linq在的测试",
                    item =
                     from p in posts
                     orderby p.Title
                     select new 
                     {
                         title=p.Title,
                         link=p.Link,

                }
            }
            );

            Console.WriteLine(o.ToString());
        }
    }
}


    3.运行的结果
