Error: This Operation cannot be performed after request has been submitted

Question

I\'ve written code about httpwebrequest and httpwebresponse . I need to send data to server but got this exception \"This operation cannot be performed

Answer 1

when you get the response stream the request is submitted so you can not the operation there...

Try it like:

HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://"+remoteServer+":8080/");
request.Credentials = CredentialCache.DefaultCredentials;
//Stream NewReqstream = request.GetRequestStream();
request.Method = "POST";
//request.ContentLength = cmd.Length;

// Send the command
//clientSocket.Send(cmd);

Stream NewReqstream = request.GetRequestStream(); //<-- Error here
NewReqstream.Write(cmd, 0, cmd.Length);
NewReqstream.Close();

// Get the response
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
Console.WriteLine("Connected..");
