100分 求解 ... HttpWebRequest 无法发送数据, 传回的值只是Re :
如果在URL直接加参数又可以正常返回值.   何解   ?     谢谢各位!  

发送代码

                string   strParm   =   "A=我晕 ";

                HttpWebResponse   result   =   null;

                Encoding   encoding   =   Encoding.GetEncoding( "GB2312 ");

                HttpWebRequest   req   =   (HttpWebRequest)WebRequest.Create( "http://localhost/Default.aspx ");

                req.ContentType   =   "application/x-www-form-urlencoded ";
                req.Method   =   "POST ";

                byte[]   SomeBytes   =   encoding.GetBytes(strParm);
                req.ContentLength   =   SomeBytes.Length;
                Stream   newStream   =   req.GetRequestStream();
                newStream.Write(SomeBytes,   0,   SomeBytes.Length);

                newStream.Close();

                result   =   (HttpWebResponse)req.GetResponse();
                StreamReader   sr   =   new   StreamReader(result.GetResponseStream(),   encoding);
                Response.Write(sr.ReadToEnd());
                sr.Close();
                result.Close();

接收代码:


<%@   Page   Language= "C# "   ValidateRequest= "false "     %>

<script   runat= "server ">

public   void   Page_Load(object   sender,   System.EventArgs   e)
{

Response.Write( "Re   :   "   +   Request.QueryString[ "username "]   )   ;
}

</script>


------解决方案--------------------
application/x-www-form-urlencoded 这种方式的数据是不能用QueryString来收的
Request.Form[ "A "]
------解决方案--------------------
在URL直接加参数又可以

就用get方法，直接传url
HttpWebRequest req = (HttpWebRequest)WebRequest.Create( "http://localhost/Default.aspx?username=testname ");
req.CookieContainer = new CookieContainer();
result = (HttpWebResponse)req.GetResponse();
