                string myUploadPath = dir;
                var myFileName = Path.GetFileName(uploadFile);

                var client = new WebClient { Credentials = CredentialCache.DefaultNetworkCredentials };

                client.UploadFile(myUploadPath + myFileName, "PUT", uploadFile);

                MessageBox.Show("ok");

                testServiceClient.Close();
            }
            catch (Exception ex)
