How to create credential object with already having access code and token for Google Drive API

I want to use same OAuth Code and Token for Both sheet and google drive api without redirecting to page 2 times for sheet and drive.

Following is the code for generating the access code and token using oauth 2

                string SCOPE = "https://spreadsheets.google.com/feeds https://docs.google.com/feeds";
                OAuth2Parameters parameters = new OAuth2Parameters();
                parameters.ClientId = CLIENT_ID;
                parameters.ClientSecret = CLIENT_SECRET;
                parameters.RedirectUri = REDIRECT_URI;
                parameters.Scope = SCOPE;
                string authorizationUrl = OAuthUtil.CreateOAuth2AuthorizationUrl(parameters); 
                OAuthUtil.GetAccessToken(parameters);
                string accessToken = parameters.AccessToken;

As in asp.net mvc its been generated through redirection for google sheet API.

I want to use google drive API for this same token also.

How i can create credential object for google Drive API in order to work with that. Following CODE OPENS ANOTHER WINDOW AND SEND CODE TO THAT WINDOW.

var credential = GoogleWebAuthorizationBroker.AuthorizeAsync(new ClientSecrets
      {
         ClientId = clientId,
         ClientSecret = clientSecret
      }, scopes, "skhan", CancellationToken.None, new FileDataStore("Drive.Auth.Store")).Result;

You can use the code below, that assumes that you already have Access/Refresh tokens:

var flow = new GoogleAuthorizationCodeFlow(new GoogleAuthorizationCodeFlow.Initializer
    {
        ClientSecrets = new ClientSecrets
            {
                ClientId = ClientId,
                ClientSecret = ClientSecret
            },
            Scopes = new[] { DriveService.Scope.Drive }
    });

var credential = new UserCredential(_flow, UserIdentifier, new TokenResponse
    {
        AccessToken = AccessToken,
        RefreshToken = RefreshToken
    });
var service = new DriveService(new BaseClientService.Initializer
    {
        ApplicationName = "MyApp",
        HttpClientInitializer = credential,
        DefaultExponentialBackOffPolicy = ExponentialBackOffPolicy.Exception | ExponentialBackOffPolicy.UnsuccessfulResponse503
    });

You can use the approach mentioned here: .NET Google api 1.7 beta authenticating with refresh token, just set on the token response your access and refersh tokens and you are ready to go.
