Как я загружаю mp3-файл в Google drive с помощью C# в MVC

---

Я успешно загрузил файл изображения в google drive с помощью C#. Но я столкнулся с проблемой загрузки mp3-файла на диск.

Что я уже пробовал:

Мой код таков :

public ServieResponse SaveFileOnGoogleDrive(string url)
       {
           //string url = string.Empty; ; ;
           //string[] scopes = new string[] { DriveService.Scope.Drive,
           //                 DriveService.Scope.DriveFile};
           string[] scopes = new string[] { DriveService.Scope.Drive,
                          DriveService.Scope.DriveAppdata,
                          //DriveService.Scope.DriveAppsReadonly,
                          DriveService.Scope.DriveFile,
                          DriveService.Scope.DriveMetadataReadonly,
                          DriveService.Scope.DriveReadonly,
                          DriveService.Scope.DriveScripts };
           var clientId = "xxxxxx";      // From https://console.developers.google.com
           var clientSecret = "xxxxxxx";

           // From https://console.developers.google.com
           // here is where we Request the user to give us access, or use the Refresh Token that was previously stored in %AppData%
           var credential = GoogleWebAuthorizationBroker.AuthorizeAsync(new ClientSecrets
           {
               ClientId = clientId,
               ClientSecret = clientSecret
           },
                                                                   scopes,
                                                                   Environment.UserName,
                                                                   CancellationToken.None,
                                                                   new FileDataStore("MyAppsToken")).Result;
           //Once consent is recieved, your token will be stored locally on the AppData directory, so that next time you wont be prompted for consent.

           DriveService service = new DriveService(new BaseClientService.Initializer()
           {
               HttpClientInitializer = credential,
               ApplicationName = "CTM",
           });

           string filePath = WebConfigurationManager.AppSettings["filPath"];
           filePath = HttpContext.Current.Server.MapPath(filePath) + url;
           uploadFile(service, filePath, "", "");

           // service.HttpClient.Timeout = TimeSpan.FromMinutes(100);
           //Long Operations like file uploads might timeout. 100 is just precautionary value, can be set to any reasonable value depending on what you use your service for.

           //return Json(new { result = "abc" }, JsonRequestBehavior.AllowGet);
           ServieResponse ob = new ServieResponse();
           ob.ResponseMsg = "Success";
           return ob;
       }

public static void uploadFile(DriveService _service, string _uploadFile, string _parent, string _descrp)
       {
           if (System.IO.File.Exists(_uploadFile))
           {
               var body = new Google.Apis.Drive.v3.Data.File();
               //File body = new File();
               body.Name = System.IO.Path.GetFileName(_uploadFile);
               body.Description = _descrp;
               body.MimeType = GetMimeType(_uploadFile);
               // body.Parents = new List<ParentReference>() { new ParentReference() { Id = _parent } };

               FilesResource.CreateMediaUpload request;
               try
               {

                   using (var stream = new System.IO.FileStream(_uploadFile, System.IO.FileMode.Open))
                   {
                       request = _service.Files.Create(body, stream, body.MimeType);
                       request.Fields = "id";
                       request.Upload();
                   }
                   var file = request.ResponseBody;
                   var fili = file.Id;
               }
               catch (Exception e)
               {

               }
           }
           else
           {

           }
       }

private static string GetMimeType(string fileName)
        {
            string mimeType = "application/unknown";
            string ext = System.IO.Path.GetExtension(fileName).ToLower();
            Microsoft.Win32.RegistryKey regKey = Microsoft.Win32.Registry.ClassesRoot.OpenSubKey(ext);
            if (regKey != null && regKey.GetValue("Content Type") != null)
                mimeType = regKey.GetValue("Content Type").ToString();
            return mimeType;
        }
