Hello

I am trying to upload a file using this code :

static void UploadFile()
      {
          string dataBoundary = "--xyz";

          HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(serverUrl);
          webRequest.ContentType = "multipart/form-data; boundary=" + dataBoundary;
          webRequest.Method = "POST";

          string datasourceStr = String.Format(
                "--{0}\r\n"
              + "Content-Disposition: form-data; name=\"datasource\"; name=\"files\"\r\n"
              + "Content-Type: application/octet-stream\r\n"
              + "\r\n",
              dataBoundary, "sample");

          string feedtypeStr = String.Format(
                "--{0}\r\n"
              + "Content-Disposition: form-data; name=\"feedtype\"; name=\"files\"\r\n"
              + "Content-Type: application/octet-stream\r\n"
              + "\r\n",
              dataBoundary, "full");

          string fileStr = String.Format(
                "--{0}\r\n"
              + "Content-Disposition: form-data; name=\"data\"; filename=\"C:\\content.txt\"\r\n"
              + "Content-Type: application/octet-stream\r\n"
              + "\r\n",
              dataBoundary, @"C:\content.txt");

          // Get the total form post size
          string totalString = datasourceStr + feedtypeStr + fileStr;
          /*
          byte[] datasourceBytes = Encoding.Default.GetBytes(datasourceStr);
          byte[] feedtypeBytes = Encoding.Default.GetBytes(feedtypeStr);
          byte[] fileBytes = Encoding.Default.GetBytes(fileStr);
          int totalBytes = datasourceBytes.Length + feedtypeBytes.Length + fileStr.Length;
          */
          byte[] totalBytes = Encoding.Default.GetBytes(totalString);
          webRequest.ContentLength = totalBytes.Length;

          // Send the data
          Stream webStream = webRequest.GetRequestStream();
          /*        webStream.Write(datasourceBytes, 0, datasourceBytes.Length);
                    webStream.Write(feedtypeBytes, 0, feedtypeBytes.Length);
                    webStream.Write(fileBytes, 0, fileStr.Length);
           */
          webStream.Write(totalBytes, 0, totalBytes.Length);
          webStream.Close();

          // Read the response
          HttpWebResponse res = (HttpWebResponse)webRequest.GetResponse();
          StreamReader sr = new StreamReader(res.GetResponseStream(), Encoding.Default);
          string backstr = sr.ReadToEnd();
          Console.Write(backstr);
          sr.Close();
          res.Close();

      }

But its giving exception at code
HttpWebResponse res = (HttpWebResponse)webRequest.GetResponse();

as:

The remote server returned an error: (405) Method Not Allowed.


Thanks
