Ajax提交Json字符串,.net反序列化成Model对象

1.创建Model对象

/// <summary>
    /// 用户实体类
    /// </summary>
    public class UserModel
    {
        /// <summary>
        /// 用户ID
        /// </summary>
        public long UserID { get; set; }

        /// <summary>
        /// 用户显示名
        /// </summary>
        public string DisplayName { get; set; }

        /// <summary>
        /// 用户名
        /// </summary>
        public string RealName { get; set; }
    }

2.创建Json序列化帮助类

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
{
    /// <summary>
    /// JsonHelper
    /// </summary>
    public class JsonHelper
    {
        /// <summary>
        /// JSON序列化
        /// </summary>
        /// <typeparam name="T"></typeparam>
        /// <param name="entity"></param>
        /// <returns></returns>
        public static string JsonSerializer<T>(T entity)
        {
            var serializer = new JavaScriptSerializer();
            return serializer.Serialize(entity);
        }

        /// <summary>
        /// JSON反序列化
        /// </summary>
        /// <typeparam name="T"></typeparam>
        /// <param name="jsonString"></param>
        /// <returns></returns>
        public static T JsonDeserialize<T>(string jsonString)
        {            
            var serializer = new JavaScriptSerializer();
            return serializer.Deserialize<T>(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<UserModel>(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
