    The following code sample calls the API's playlistItems.list method to retrieve a list of videos uploaded to the channel associated with the request. The code also calls the channels.list method with the mine parameter set to true to retrieve the playlist ID that identifies the channel's uploaded videos.

    I hate .NET and I have been fighting with this for weeks. Some of the problems I encountered;

    1. a faulty pair of API Keys, they just didn't work. I guess it was a random bug.
    2. I also have a couple MP4's that I downloaded from Youtube that would not upload back, within creator studio they would say "Upload failed: Can't process file" I determined this by attempting to upload them in the youTube interface. (not through API)
    3. async vs. synchronous was causing me many issues I just don't understand.

    I would like to improve this code to provide actual upload status/feedback but I think that would need to be done client side. I am not very good at C#/.NET

    UPDATE here is my feedback code via server & client side - https://stackoverflow.com/a/49516167/3790921

    I have made some minor changes to your code, its best to get your initial example of Oauth2 working first. Its hard to tell why you are getting an access denied. Here is what i have changed.

    1. "user" i have changed to Environment.UserName this way your credentials name will be the name of the current logged in user.
    2. I have changed the location of your FileDataStore I am not all that sure that the code you were using was going to work. Mine will store the credentials in a new directory in the current working directory.

    Info on the user parameter it is just used to create the credentials fine in the directory submitted to FileDataStore.

    Google.Apis.Auth.OAuth2.Responses.TokenResponse-lilaw

    My login user name is lilaw in this manner you can have credentials files for each user. Being that this is a console application that doesn't matter much.

    What you should check if this does not work out of the box:

    1. When you created your client on Google developer console make sure it was type other. You cant use a console application with browser credentials and you cant use the YouTube API with a service account.
    2. Remember that the YouTube API channel based so when you login you pick a channel you will only have access to that channel.

    Tip: If you want to log out the current user or force it to login again. Just change Environment.UserName to something else it will force it to login again

    I have tested this code it works:

    using Google.Apis.Auth.OAuth2;
    using Google.Apis.Services;
    using Google.Apis.Util.Store;
    using Google.Apis.YouTube.v3;
    using Google.Apis.YouTube.v3.Data;
    using System;
    using System.IO;
    using System.Threading;
    using System.Threading.Tasks;
    
    namespace TestYoutube
    {
        class Program
        {
            [STAThread]
            static void Main(string[] args)
            {
                Console.WriteLine("YouTube Data API: Playlist Updates");
                Console.WriteLine("==================================");
    
                try
                {
                    new Program().Run().Wait();
                }
                catch (AggregateException ex)
                {
                    foreach (var e in ex.InnerExceptions)
                    {
                        Console.WriteLine("Error: " + e.Message);
                    }
                }
    
                Console.WriteLine("Press any key to continue...");
                Console.ReadKey();
            }
    
            private async Task Run()
            {
                UserCredential credential;
                using (var stream = new FileStream("client_secrets.json", FileMode.Open, FileAccess.Read))
                {
                    credential = await GoogleWebAuthorizationBroker.AuthorizeAsync(
                        GoogleClientSecrets.Load(stream).Secrets,
                        new[] { YouTubeService.Scope.Youtube },
                        Environment.UserName,
                        CancellationToken.None,
                        new FileDataStore($"{Directory.GetCurrentDirectory()}/credentials")
                    );
                }
    
                var youtubeService = new YouTubeService(new BaseClientService.Initializer()
                {
                    HttpClientInitializer = credential,
                    ApplicationName = this.GetType().ToString()
                });
    
                // Create a new, private playlist in the authorized user's channel.
                var newPlaylist = new Playlist
                {
                    Snippet = new PlaylistSnippet
                    {
                        Title = "Test Playlist",
                        Description = "A playlist created with the YouTube API v3"
                    },
                    Status = new PlaylistStatus {PrivacyStatus = "public"}
                };
                newPlaylist = await youtubeService.Playlists.Insert(newPlaylist, "snippet,status").ExecuteAsync();
    
                // Add a video to the newly created playlist.
                var newPlaylistItem = new PlaylistItem
                {
                    Snippet = new PlaylistItemSnippet
                    {
                        PlaylistId = newPlaylist.Id,
                        ResourceId = new ResourceId
                        {
                            Kind = "youtube#video",
                            VideoId = "GNRMeaz6QRI"
                        }
                    }
                };
                newPlaylistItem = await youtubeService.PlaylistItems.Insert(newPlaylistItem, "snippet").ExecuteAsync();
    
                Console.WriteLine("Playlist item id {0} was added to playlist id {1}.", newPlaylistItem.Id, newPlaylist.Id);
            }
        }
    }
    

    Once you have that working there are several examples here one is for upload video
