将视频从iOS设备上传到youtube Xamarin iOS

Question

//我的将凭据分配给youtubeService的代码：

  TokenResponse token = new TokenResponse();

  token.AccessToken = e.User.Authentication.AccessToken;

  token.IssuedUtc = DateTime.Now;

  var time = e.User.Authentication.AccessTokenExpirationDate.SecondsSinceReferenceDate.ToString();  

string[] parts = time.Split('.');

int i1 = int.Parse(parts[0]);

int i2 = int.Parse(parts[1]);

token.ExpiresInSeconds = long.Parse(i1.ToString());

 ClientSecrets clientSecrets = new ClientSecrets();

clientSecrets.ClientId = e.User.Authentication.ClientId;

GoogleAuthorizationCodeFlow.Initializer initializer = new GoogleAuthorizationCodeFlow.Initializer();

initializer.ClientSecrets = clientSecrets;

credential = new UserCredential(new Google.Apis.Auth.OAuth2.Flows.GoogleAuthorizationCodeFlow(initializer), e.User.UserID, token);

 youtubeService = new YouTubeService(new BaseClientService.Initializer()
            {
                HttpClientInitializer = credential
            });

            video.Snippet = new VideoSnippet();
            video.Snippet.Title = "Default Video Title";
            video.Snippet.Description = "Default Video Description";
            video.Snippet.Tags = new string[] { "tag1", "tag2" };
            video.Status = new VideoStatus();
            video.Status.PrivacyStatus = "private"; // or "private" or "public"
            using (var fileStream = new FileStream(pathString, FileMode.Open))
            {
                var videosInsertRequest = youtubeService.Videos.Insert(video, "snippet,status", fileStream, "video/*");
                videosInsertRequest.ProgressChanged += videosInsertRequest_ProgressChanged;
                videosInsertRequest.ResponseReceived += videosInsertRequest_ResponseReceived;
                 videosInsertRequest.UploadAsync();
            }

//但是我在上传视频时遇到了问题。错误如下：

An error prevented the upload from completing.

//可能是在将凭据分配给YouTubeService时发生此错误。让我知道是否有人遇到这种问题。
