Answer 1

The best solution I found so far is:

void MyFunc(CancellationToken ct)
{
  //...
  var timedOut = WaitHandle.WaitAny(new[] { ct.WaitHandle }, TimeSpan.FromMilliseconds(2000)) == WaitHandle.WaitTimeout;
  var cancelled = ! timedOut;
}

UPDATE:

The best solution so far is the accepted answer.
