Google drive Redirect URI Mismatch and how to get files list from google drive in ASP.net core 2.0

In my project, I want to get google drive file lists into my project. I am using ASP.NET Core.

I created a project in Google API Console successfully and implemented the code in ASP.NET core. I got Redirect URI Mismatch error every time when I run the program even I set redirect URL properly. I didn't get success.

I am using Google drive API V3.

That’s an error. Error: redirect_uri_mismatch

The redirect URI in the request, http://127.0.0.1:63354/authorize/, does not match the ones authorized for the OAuth client.

So I following below steps for my ASP.NET core project. (First I tried in console project and I got success) https://dzone.com/articles/authentication-using-google-in-aspnet-core-20

By this link, I can authenticate in google but I am not able to get files list from google drive. I am not getting any error and got files to count as zero.

        public IActionResult Authenticate()
        {
            UserCredential credential = GoogleWebAuthorizationBroker.AuthorizeAsync(
               new ClientSecrets
               {

               CancellationToken.None).Result;


            var service = new DriveService(new BaseClientService.Initializer()
            {
                HttpClientInitializer = credential,
                ApplicationName = "WebApplication3",
            });

            FilesResource.ListRequest listRequest = service.Files.List();
            listRequest.PageSize = 10;
            listRequest.Fields = "nextPageToken, files(id, name)";


            IList<Google.Apis.Drive.v3.Data.File> files = listRequest.Execute()
                 .Files;

            ViewBag.filecount = files.Count;

            if (files != null && files.Count > 0)
            {
                foreach (var file in files)
                {
                   ViewBag.fileName = file.Name;
                }
            }
            return View("Test");

        }
    }
}
