1.项目引用NuGet包；搜索：Newtonsoft.Json

2.序列号实例

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;using System.Data;namespace JsonConvert{    class Program    {        static void Main(string[] args)        {            //js传递过程可直接将数据或者对象转成字符串进行传递            string msg = "{*****}";//将对象字符串转成相应的对象            //DeserializeObject
     
       是一个泛型。            var model =  Newtonsoft.Json.JsonConvert.DeserializeObject
      
       (msg);            //将对象转成字符串            DataTable dt = new DataTable();            msg = Newtonsoft.Json.JsonConvert.SerializeObject(dt);        }    }}
      
     

3.常用api抛出数据实现类

 

using Newtonsoft.Json;using System;using System.Collections.Generic;using System.Linq;using System.Web;namespace JsonConvert{    public class ReturnResult
     
          {        public T data;        public int status;        public string Msg;        /// 
      
        ///         /// 
        /// 
      数据实体        /// 
      1：成功，0：失败        public ReturnResult(T data, int stauts = 1,string msg="成功")        {            this.data = data;            this.status = stauts;            this.Msg = msg;        }        /// 
      
        /// 序列化        /// 
        /// 
              public string Serialize()        {            return JsonConvert.SerializeObject(this);        }    }}
