反序列化实体

悬赏园豆:5 [已关闭问题]

这里是一个实体类

[DataContract(Name="UserInfo")]
public class User
{
[DataMember(Name
= "ID")]
public string UserID{get;set;}

[DataMember(Name
="Name")]
public string UserName { get; set; }

[DataMember(Name
="Pwd")]
public string UserPwd { get; set; }

[DataMember(Name
="Sex")]
public bool Sex { get; set; }

[DataMember(Name
="Age")]
public int Age { get; set; }
}

通过AJAX发送回数据
{
"CalssName":"UserInfo",
"ClassData":"{"ID":"530332","Name":"张三","Pwd":"123456","Sex":"0","Age":"20"}"
}
怎么样把它"反序列化"
来生成一个User实体对象
问题补充: 这个和反射有什么关系吗? 我的名称空间是GradView.Lib.Data(实体) 前台发回来的Ajax数据可以改变结构.

你可以在MSDN中搜索关于JavaScriptSerializer的信息

也可以参考这篇文章 http://www.cnblogs.com/myssh/archive/2009/07/07/1518758.html

使用 LinqToJOSN
