  {

  string url=www.xxx123/logion.asp;
   this.post(url,"username","admin","passwd","admin");
  }

 //post方法
  public void post(string url,string name,string namevalue,string password,string passwordvalue)
  { 
   Response.Write(@"
   <form id=""form1"" action=""" +url+ @""" method=""post"">
   <input type=""hidden"" name="""+name+@""" value="""+namevalue+@""">
   <input type=""hidden"" name="""+password+@""" value="""+passwordvalue+@""">

   <script language=""javascript"">
   document.getElementById('form1').submit();
