using System.Threading.Tasks;

namespace ConsoleApp1
{
    internal class Program
    {
        static async Task Main(string[] args)
        {
            ;
            var credentials = await GoogleCredential.FromFileAsync("key/mobileprice-389203-a6dc6ada2693.json", CancellationToken.None);
            var service = new DriveService(new BaseClientService.Initializer());
            Console.WriteLine("success");
            var metadata = new Google.Apis.Drive.v3.Data.File() { Name = "myfile.txt" };
            //var mediacontent = new MemoryStream(System.IO.TextWriter("hello world"));
            //var uploadRequest = service.Files.Create(metadata, mediacontent, "text/plain");
            var uploadRequest = service.Files.Create(metadata);
            uploadRequest.Fields = "id";
            var file = uploadRequest.Execute();

Create it locally and then move it.

Another clear error message: you need to be authorised.

Check the documentation for the Google service you are using.

I don't know anything about Google service API's since I have no need to use them, just looking at your code, it would appear that you're creating a credential object, but you never use it or pass it to any service function. That would probably be why you're getting the error message.

You're going to have to read the documentation on the service you're trying to use so you can understand how to pass credentials or your credential object to it, thereby authorizing the call.
