C#中使用Newtonsoft.Json序列化和反序列化自定义类对象

C#中使用Newtonsoft.Json序列化和反序列化自定义类对象

在C#中序列化和反序列化自定义的类对象是比较容易的，比如像下面的一个Customer类，

private class Customer
{
    public string CustomerName { get; set; }
    public string Email { get; set; }
    public int Age { get; set; }
    public decimal TotalSales { get; set; }
    public DateTime FinalPurchaseDate { get; set; }
}

在Windows10系统中使用VS2017创建一个基于C#控制台的.Net控制台应用程序JsonExample01，
然后使用NuGet安装Newtonsoft.Json的包，

下面是相关的C#测试代码：

using Newtonsoft.Json;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace JsonExample01

{

class Program

{

static void Main(string[] args)

{

var customers = new List<Customer>

{

new Customer

{

CustomerName = "John",

Age = 33,

Email = "john@gmail.com",

TotalSales = 4000,

FinalPurchaseDate = new DateTime(2021, 3, 29)

},

new Customer

{

CustomerName = "George",

Age = 32,

Email = "george@gmail.com",

TotalSales = 6000,

FinalPurchaseDate = new DateTime(2021, 3, 29)

},

new Customer

{

CustomerName = "Peter",

Age = 28,

Email = "john@gmail.com",

TotalSales = 2000,

FinalPurchaseDate = new DateTime(2021, 1, 10)

}

};
        var customer = new Customer
        {
            CustomerName = "Peter",
            Age = 28,
            Email = "john@gmail.com",
            TotalSales = 2000,
            FinalPurchaseDate = new DateTime(2021, 1, 10)
        };

        var customerJson1 = JsonConvert.SerializeObject(customer);
        Console.WriteLine(customerJson1);

        var customerListJson2 = JsonConvert.SerializeObject(customers);
        Console.WriteLine(customerListJson2);

        //var strJson1 = "{\"CustomerName\":\"Peter\",\"Email\":\"john@gmail.com\",\"Age\":28,\"TotalSales\":2000.0,\"FinalPurchaseDate\":\"2021-01-10T00:00:00\"}";
        //var customer2 = JsonConvert.DeserializeObject&lt;Customer&gt;(strJson1);

        //var strJson = "[{\"CustomerName\":\"John\",\"Email\":\"john@gmail.com\",\"Age\":33,\"TotalSales\":4000.0,\"FinalPurchaseDate\":\"2021-03-29T00:00:00\"},{\"CustomerName\":\"George\",\"Email\":\"george@gmail.com\",\"Age\":32,\"TotalSales\":6000.0,\"FinalPurchaseDate\":\"2021-03-29T00:00:00\"},{\"CustomerName\":\"Peter\",\"Email\":\"john@gmail.com\",\"Age\":28,\"TotalSales\":2000.0,\"FinalPurchaseDate\":\"2021-01-10T00:00:00\"}]";
        //var customerList2 = JsonConvert.DeserializeObject&lt;List&lt;Customer&gt;&gt;(strJson);

        var strJson1 = "{\"customer_name\":\"Peter\",\"email\":\"john@gmail.com\",\"age\":28,\"total_sales\":2000.0,\"final_purchase_date\":\"2021-01-10T00:00:00\"}";
        var customer2 = JsonConvert.DeserializeObject&lt;Customer&gt;(strJson1);

        var strJson = "[{\"customer_name\":\"John\",\"email\":\"john@gmail.com\",\"age\":33,\"total_sales\":4000.0,\"final_purchase_date\":\"2021-03-29T00:00:00\"},{\"customer_name\":\"George\",\"email\":\"george@gmail.com\",\"age\":32,\"total_sales\":6000.0,\"final_purchase_date\":\"2021-03-29T00:00:00\"},{\"customer_name\":\"Peter\",\"email\":\"john@gmail.com\",\"age\":28,\"total_sales\":2000.0,\"final_purchase_date\":\"2021-01-10T00:00:00\"}]";
        var customerList2 = JsonConvert.DeserializeObject&lt;List&lt;Customer&gt;&gt;(strJson);

        Console.ReadKey();
    }

    [Serializable]
    private class Customer
    {
        [JsonProperty("customer_name")]
        public string CustomerName { get; set; }
        [JsonProperty("email")]
        public string Email { get; set; }
        [JsonProperty("age")]
        public int Age { get; set; }
        [JsonProperty("total_sales")]
        public decimal TotalSales { get; set; }
        [JsonProperty("final_purchase_date")]
        public DateTime FinalPurchaseDate { get; set; }
    }
}
