紧急求救，还没睡的朋友帮忙看看
ASCIIEncoding encoding = new ASCIIEncoding();
string postData = "TextBox1=test ";
// postData += ( "&Button2=Cookie ");

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

// Prepare web request...
HttpWebRequest myRequest =
(HttpWebRequest)WebRequest.Create( "http://localhost:1708/test/slogin.aspx ");

myRequest.Method = "POST ";
myRequest.ContentType = "application/x-www-form-urlencoded ";
myRequest.ContentLength = data.Length;
myRequest.AllowAutoRedirect = true;
Stream newStream = myRequest.GetRequestStream();


// Send the data.
newStream.Write(data, 0, data.Length);
newStream.Close();

// Get response
HttpWebResponse myResponse = (HttpWebResponse)myRequest.GetResponse();
StreamReader reader = new StreamReader(myResponse.GetResponseStream(), Encoding.Default);
string content = reader.ReadToEnd();
Response.Write(content);
