--------------------编程问答-------------------- 不是大神，坐等大神

--------------------编程问答-------------------- 添加个webservice引用直接可以掉这个方法啊，就像掉本地的方法一样。

或者可以参见我在这个帖子中的回复（7楼）
使用HttpWebRequest发送POST/GET请求获取网页数据 --------------------编程问答-------------------- 这个方法我以前用来调用java 的一个services，你可以试试
string param = "hl=zh-CN&newwindow=1";
   byte[] bs = Encoding.ASCII.GetBytes(param);

   HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create("http://duilian.msra.cn/app/couplet.aspx");
   req.Method = "POST";
   req.Accept = "text/html, application/xhtml+xml, */*";
   req.Referer = "http://duilian.msra.cn/app/couplet.aspx";
   req.ContentType = "application/json; charset=UTF-8";

   req.ContentLength = 72;

   req.Host = "duilian.msra.cn";
   string name ="name";
   req.Headers.Add(name, "http://duilian.msra.cn/app/CoupletsWS_V2.asmx/GetXiaLian");

   using (Stream reqStream = req.GetRequestStream())
   {
         reqStream.Write(bs, 0, bs.Length);
   }
   using (WebResponse wr = req.GetResponse())
   {
         //在这里对接收到的页面内容进行处理
   }

补充：.NET技术 ,  Web Services
