using System.Runtime.Serialization.Json;
using System.ServiceModel.Web;///记得引用这个命名空间
/// <summary>
/// 把JSON字符串还原为对象
/// </summary>
/// <typeparam name="T">对象类型</typeparam>
/// <param name="szJson">JSON字符串</param>
/// <returns>对象实体</returns>
public static T ParseFormJson<T>(string szJson)
{
T obj = Activator.CreateInstance<T>();
using (MemoryStream ms = new MemoryStream (Encoding.UTF8.GetBytes(szJson)))
{
DataContractJsonSerializer dcj = new DataContractJsonSerializer(typeof(T));
return (T)dcj.ReadObject(ms);
}
}

后台先从request里读取parameter的值，然后作为szJson参数变量调用ParseFormJson解析。
