Each detached nested task invoked by the Parallel.ForEach<'TSource> loop checks the state of the cancellation token and, if cancellation is requested, calls the CancellationToken.ThrowIfCancellationRequested method. The CancellationToken.ThrowIfCancellationRequested method throws an OperationCanceledException exception that is handled in a catch block when the calling thread calls the Task.Wait method.method to create a task that iterates the files in the C:\Windows\System32 directory.
