            }

        }

调用方法

HttpPost("http://www.luofenming.com/Getdata.ashx", "userName= userName &Password=password");
//注意 URL是一个服务地址格式不要写错了

以上是客户端，下面是服务端 http://www.luofenming.com/Getdata.ashx代码

<%@ WebHandler Language="C#" Class="getData" %>
using System;
using System.Web;

public class getData : IHttpHandler {

    public void ProcessRequest (HttpContext context) {
        context.Response.ContentType = "text/plain";
        string userName = context.Request["userName"];//接收客户端发来的数据userName=123&Password=456
        string Password = context.Request["password"];
        context.Response.Write("接收成功，内容为userName:"+userName+"passWord:"+Password);//响应发送端
    }
    public bool IsReusable {
        get {
            return false;
        }
    }
}
