youtube api token upload video

Question

I am retriving a token through an website, then I save the token, and refresh token in a database. Then I am writing .net program that uploads video's located on our server to youtube. My problem is to get the program I am making, use the stored token. I am using one of google's examples to upload the video. But the program should use the already saved token, instead os asking for new credentials.

The current code is this.

UserCredential credential;

        //credential.UserCredential(,"",)

        using (var stream = new FileStream("client_secrets.json", FileMode.Open, FileAccess.Read))
        {
            credential = await GoogleWebAuthorizationBroker.AuthorizeAsync(
                GoogleClientSecrets.Load(stream).Secrets,
                // This OAuth 2.0 access scope allows an application to upload files to the
                // authenticated user's YouTube channel, but doesn't allow other types of access.
                new[] { YouTubeService.Scope.YoutubeUpload },
                "user",
                CancellationToken.None
            );

        }
        Console.WriteLine("HER");

        var youtubeService = new YouTubeService(new BaseClientService.Initializer()
        {
            HttpClientInitializer = credential,
            ApplicationName = Assembly.GetExecutingAssembly().GetName().Name
        });

So instead I would like to use an already saved token.

Any help, or a pointer in the right direction would be great. Thanks.

You would use GoogleAuthorizationCodeFlow instead of GoogleWebAuthorizationBroker in order to use the refresh token. See the answer here.
