我可以上传没有附件的电子邮件，但我无法上传附件中的电子邮件。
是否有任何来源我可以查看有关如何操作的源代码？
或者可以为我提供任何可以完成项目的指针/代码存根吗？
我目前正在使用Visual Studio 2010的Nuget库。
以下是我的代码无效：
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)

下面是Fiddler Stack trace：
