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

/* ==============================================================================
* 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
{
/// <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
