Async long running process

Question

I have a question about a scenario I need to code. I have a process that will send a request file via SFTP and then I will need to wait for a response file to be created on the ftp server before I download and continue my processing. The response file could take anywhere between 1min to 60mins to appear. If I await this process, is there a way that I can say, give up after 60 mins? C#

You could add an CancelationToken with a duration of 60Minutes — TheTanic, Mar 16 '22 at 09:50
How are you sending the request file via SFTP? Is the send operation cancellable? — Theodor Zoulias, Mar 16 '22 at 10:00
^^ Also, it would be interesting how you track and wait for the "response file" to appear. Best would be to post the relevant code. — Fildor, Mar 16 '22 at 10:03

Use a CancellationTokenSource

private CancellationTokenSource _cancellationTokenSource =
    new CancellationTokenSource(TimeSpan.FromMinutes(60));

Wrap the code in a try/catch and watch for TaskCanceledException

Also, check out Asynchronously wait for Task to complete with timeout
