Не удалось перенести электронную почту с помощью вложений с помощью API электронной почты электронной почты Google V2 с библиотекой Nuget в C#

Question

Я могу загружать электронные письма, у которых нет вложений, но я не могу загружать электронные письма с прикрепленными файлами.

Есть ли источник, в котором я могу посмотреть исходный код, как это сделать?

Или может предоставить мне любые указатели/заглушки кода, с помощью которых я могу завершить проект?

настоящее время я использую библиотеку NuGet с Visual Studio 2010.

После мой код, который не работает:

private Task Run() 
{ 
UserCredential cred; 
cred = GoogleWebAuthorizationBroker.AuthorizeAsync(new ClientSecrets 
      { 
       ClientId = "ClientID", 
       ClientSecret = "ClientSecret", 
      }, new[] { Google.Apis.Admin.email_migration_v2.AdminService.Scope.EmailMigration }, "admin@example.com", System.Threading.CancellationToken.None,new FileDataStore("Email.Migration")).Result; 

var service = new AdminService(new Google.Apis.Services.BaseClientService.Initializer 
      { 
       ApplicationName = "Email Migration", 
       HttpClientInitializer = cred 
      }); 

     return UploadFileAsync(service); 
} 

private Task<IUploadProgress> UploadFileAsync(AdminService service) 
    { 
MailItem mailitem = new MailItem(); 
mailitem.IsInbox = true;

byte[] byteArray = Encoding.UTF8.GetBytes(BodyContent); 
MemoryStream stream = new MemoryStream(byteArray); 

String ContentType = "multipart/related; boundary=\"part_boundary\""; 

    var insert = service.Mail.Insert(mailitem, "abc@example.com", stream, ContentType); 
     insert.ProgressChanged += new Action<Google.Apis.Upload.IUploadProgress> (irm_ProgressChanged); 
     insert.ChunkSize = MailResource.InsertMediaUpload.DefaultChunkSize * 2; 
     var task = insert.UploadAsync(); 
     task.ContinueWith(t => 
     { 
      // NotOnRanToCompletion - this code will be called if the upload fails 

     }, TaskContinuationOptions.NotOnRanToCompletion); 
     task.ContinueWith(t => 
     { 

      stream.Dispose(); 

     }); 
     return task; 
    } 

    private void irm_ProgressChanged(Google.Apis.Upload.IUploadProgress progress) 
    { 
     try 
     { 
      if (progress.Exception != null) 
      { 
       MessageBox.Show(progress.Exception.Message); 
      } 

     } 
     catch (Exception ex) 
     { 
      throw ex; 
     } 
    }

Источник код here

Я вижу, что вы уже используете this, и вы следовали these

BUT .. можете ли вы приложить точную ошибку, которую вы получаете, и трассировку стеллажа?
