Get current running Task

Question

Is this possible to get current running Task and cancel it in other places which there is no access to Task object? Let's say I started a Task in classA and I want to cancel it in classB , is there anyway to find current Task and cancel it?

Answer 1

No, there is no notion of a current Task . There are arbitrarily many tasks running at the same time. Even "running" is not well defined. Is new TaskCompletionSource<object>().Task running or is it not?

Create a cancellable CancellationToken and pass it to the task to make it self-cancel. Pass the underlying CancellationTokenSource to the code that wants to cancel.
