C＃桌面应用程序。简单的例子，如何将文件上传到谷歌驱动器[关闭](C# Desktop app

是否有一个桌面应用程序如何授权给谷歌云端硬盘服务和上传文件的任何代码的例子吗？

目前，我有：

var parameters = new OAuth2Parameters
                                 {
                                     ClientId = ClientCredentials.ClientId,
                                     ClientSecret = ClientCredentials.ClientSecret,
                                     RedirectUri = ClientCredentials.RedirectUris[0],
                                     Scope = ClientCredentials.GetScopes()
                                 };    
string url = OAuthUtil.CreateOAuth2AuthorizationUrl(parameters);
    // Open url, click to allow and copy secret code
    parameters.AccessCode = secretCodeFromBrowser;
    OAuthUtil.GetAccessToken(parameters);
    string accessToken = parameters.AccessToken;
    // So, there is the access token

但什么是下一个步骤是什么？当我从实例看，我应该得到IAuthenticator实例，并将其传递到DriveService类的构造函数......如何获得IAuthenticator的实例？如果我上面的代码是正确的...在此先感谢。

这是在C＃中一个完整的命令行样本文件上传到谷歌驱动器：

            String CLIENT_SECRET = "YOUR_CLIENT_SECRET";

            // Register the authenticator and create the service
            var provider = new NativeApplicationClient(GoogleAuthenticationServer.Description, CLIENT_ID, CLIENT_SECRET);
            var auth = new OAuth2Authenticator<NativeApplicationClient>(provider, GetAuthorization);

            FilesResource.InsertMediaUpload request = service.Files.Insert(body, stream, "text/plain");
            request.Upload();

            File file = request.ResponseBody;
            Console.WriteLine("File id: " + file.Id);
            Console.ReadLine();
        }

        private static IAuthorizationState GetAuthorization(NativeApplicationClient arg)
        {
            // Get the auth URL:
            IAuthorizationState state = new AuthorizationState(new[] { DriveService.Scopes.Drive.GetStringValue() });
            state.Callback = new Uri(NativeApplicationClient.OutOfBandCallbackUrl);
            Uri authUri = arg.RequestUserAuthorization(state);

            // Request authorization from the user (by opening a browser window):
            Process.Start(authUri.ToString());
            Console.Write("  Authorization Code: ");
            string authCode = Console.ReadLine();
            Console.WriteLine();

            // Retrieve the access token by using the authorization code:
            return arg.ProcessUserAuthorization(authCode, state);
        }
    }
}
