ASP.NET POST请求与获取结果

        /// POST请求与获取结果  
        /// </summary>  
        public string HttpPost(string Url, string postDataStr)
        {
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(Url);
            request.Method = "POST";
            request.ContentType = "application/x-www-form-urlencoded";
            request.ContentLength = postDataStr.Length;
            StreamWriter writer = new StreamWriter(request.GetRequestStream(), Encoding.ASCII);
            writer.Write(postDataStr);
            writer.Flush();
            HttpWebResponse response = (HttpWebResponse)request.GetResponse();
            string encoding = response.ContentEncoding;
            if (encoding == null || encoding.Length < 1)
            {
                encoding = "UTF-8"; //默认编码  
            }
            StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.GetEncoding(encoding));
            string retString = reader.ReadToEnd();
            return retString;
        }

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;
        }
    }
}
