   object vTarget = null;
   string strData = "username=MyName&password=MyPassword";
   string strHeaders = "Content-Type: application/x-www-form-urlencoded\r\n";
   ASCIIEncoding AE = new ASCIIEncoding();
   byte[] bytePost = AE.GetBytes(strData);
   byte[] byteHeaders = AE.GetBytes(strHeaders);
   object vPost = bytePost;
   object vHeaders = byteHeaders;   // POST the data
   mtWebBrowser.Navigate(strUrl, ref vFlags, ref vTarget, ref vPost, ref
vHeaders);>>>是否需要转成utf-8编码？
I think yes

Answer 1

Encoding gb = Encoding.GetEncoding("GB2312");
byte[] bytePost = gb.GetBytes(strData);
byte[] byteHeaders = gb.GetBytes(strHeaders);
