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.

不会AJAX,帮你顶，留个印。

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

Type type = typeof(T);
object instance = Activator.CreateInstance(type);
foreach (PropertyInfo property in type.GetProperties())
{
if (property.CanWrite)
{
object value = classData[property.Name];
if (value != null)
{
property.SetValue(instance, value, null);
}
}
}
return (T)Convert.ChangeType(instance, typeof(T));
}
}

使用 LinqToJOSN
