请教  
                        Stream   newStream=myRequest.GetRequestStream();
                        //   Send   the   data.
                        newStream.Write(data,0,data.Length);
提交的data部分   如何写

------解决方案--------------------
string postData = "action=login ";
postData += "&username=solo ";
postData += "&PWD=testpassword ";

System.Text.Encoding encoding = System.Text.Encoding.GetEncoding( "GB2312 ");
byte[] data = encoding.GetBytes(postData);
