Newtonsoft.Json序列化和反序列之javascriptConvert.SerializeObject，DeserializeObject，JsonWriter，JsonReader

这里下载:http://www.newtonsoft.com/products/json/
安装:
   1.解压下载文件,得到Newtonsoft.Json.dll
   2.在项目中添加引用..

javascriptConvert.SerializeObject

 序列化和反序列在.net项目中: 

Product product = new Product(); 

product.Name = "Apple";

product.Expiry = new DateTime(2008, 12, 28);

product.Price = 3.99M;

product.Sizes = new string[] { "Small", "Medium", "Large" };

string output = javascriptConvert.SerializeObject(product);

//{

//  "Name": "Apple",

//  "Expiry": new Date(1230422400000),

//  "Price": 3.99,

//  "Sizes": [

//    "Small",

//    "Medium",

//    "Large"

//  ]

//}

javascriptConvert.DeserializeObject

Product deserializedProduct = (Product)javascriptConvert.DeserializeObject(output, typeof(Product));

  
读取JSON

string jsonText = "['JSON!',1,true,{property:'value'}]"; 

JsonReader reader = new JsonReader(new StringReader(jsonText)); 

Console.WriteLine("TokenType		ValueType		Value"); 

while (reader.Read())
{

    Console.WriteLine(reader.TokenType + "		" + WriteValue(reader.ValueType) + "		" + WriteValue(reader.Value))

}

结果显示:

TokenType	ValueType	Value
StartArray	null	null
String	System.String	JSON!
Integer	System.Int32	1
Boolean	System.Boolean	True
StartObject	null	null
PropertyName	System.String	property
String	System.String	value
EndObject	null	null
EndArray	null	null

 

 

 

 

 

 

JSON写入

StringWriter sw = new StringWriter();

JsonWriter writer = new JsonWriter(sw); 

writer.WriteStartArray();

writer.WriteValue("JSON!");

writer.WriteValue(1);

writer.WriteValue(true);

writer.WriteStartObject();

writer.WritePropertyName("property");

writer.WriteValue("value");

writer.WriteEndObject();

writer.WriteEndArray(); 

writer.Flush(); 

string jsonText = sw.GetStringBuilder().ToString(); 

Console.WriteLine(jsonText);

// ['JSON!',1,true,{property:'value'}]

这里会打印出: ['JSON!',1,true,{property:'value'}].
