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

string lcUrl ="http://192.168.1.1/index.php";

string lcPostData = "cmd=client_login"+"&"+"user="+user+"&"+"pass="+pwd;





byte[] data = encoding.GetBytes(lcPostData);

HttpWebRequest loHttp =(HttpWebRequest)WebRequest.Create(lcUrl);
loHttp.Method="POST";
loHttp.ContentType="application/x-www-form-urlencoded";
loHttp.ContentLength = lcPostData.Length;
Stream newStream=loHttp.GetRequestStream();//就是在这一步出错



newStream.Write(data,0,data.Length);
newStream.Close();
