1.创建Model对象

/// 
    /// 用户实体类    /// 
    public class UserModel    {        /// 
        /// 用户ID        /// 
        public long UserID { get; set; }        /// 
        /// 用户显示名        /// 
        public string DisplayName { get; set; }        /// 
        /// 用户名        /// 
        public string RealName { get; set; }    }

2.创建Json序列化帮助类

/* ============================================================================== * 功能描述：JsonHelper   * 创 建 者：RES-WUZHOU * 创建日期：2012/6/21 17:17:08 * ==============================================================================*/using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Runtime.Serialization.Json;using System.IO;using System.Web.Script.Serialization;namespace Common{    /// 
    /// JsonHelper    /// 
    public class JsonHelper    {        /// 
        /// JSON序列化        /// 
        /// 
             ///         /// 
             public static string JsonSerializer
     
      (T entity)        {            var serializer = new JavaScriptSerializer();            return serializer.Serialize(entity);        }        /// 
      
        /// JSON反序列化        /// 
        /// 
              /// 
              /// 
              public static T JsonDeserialize
      
       (string jsonString)        {                        var serializer = new JavaScriptSerializer();            return serializer.Deserialize
       
        (jsonString);        }    }}
       
      
     

注意:手动引用 System.Web.Script.Serialization.dll

3.后台 CS方法

public ActionResult Add(string strUserModel)        {            UserModel userModel = JsonHelper.JsonDeserialize
     
      (strUserModel);    //....        }
     

4.前台ajax提交

var userModel = {};userModel.UserID=1;userModel.DisplayName = "张三";userModel.RealName= "zhang";$.ajax({                url: "/user/add",                type: "post",                data: { strUserModel: $.toJSON(userModel) },                success: function (json) {                                         alert('成功');                },                error: function () {                    alert("系统异常!");                }            });

注意：页面需引用jquery.js和jquery.json.js
