我有以下代码:

private void GetRequestStreamCallback(IAsyncResult asynchronousResult)
        {
            HttpWebRequest request = (HttpWebRequest)asynchronousResult.AsyncState;

            // End the operation
            Stream postStream = request.EndGetRequestStream(asynchronousResult);

            //Console.WriteLine("Please enter the input data to be posted:");
            //string postData = Console.ReadLine();
            string postData = "my data";

            // Convert the string into a byte array.
            byte[] byteArray = Encoding.UTF8.GetBytes(postData);

            // Write to the request stream.
            postStream.Write(byteArray, 0, postData.Length);
            postStream.Close();

                // Start the asynchronous operation to get the response
                IAsyncResult result =
                      (IAsyncResult)request.BeginGetResponse(new AsyncCallback(GetResponseCallback), request);

        }

        private void GetResponseCallback(IAsyncResult asynchronousResult)
        {
            HttpWebRequest request …
