How to abort a file transfer in the middle?

[JgBr123]

I see that it was mentioned before that a file transfer could be aborted by throwing an exception in the progressCallback. The problem is that i couldn't manage to do that, as the exception is not passed to the UploadFileAsync method, and instead is thrown into my main thread.

yes, you also have to try..catch around your UploadFileAsync obviously

example with download:

var cts = new CancellationTokenSource(); // some other thread/task may trigger the cts.Cancel()
try
{
	using var fs = new FileStream("download.bin", FileMode.Create);
	await Client.DownloadFileAsync(document, fs, progress: (progress, total) => cts.Token.ThrowIfCancellationRequested());
}
catch (OperationCanceledException ex)
{
	Console.WriteLine("Transfer was aborted");
}
