How to cancel a parallel task

a) THREAD A:  The method for the starting of the parallel task instantiates a new System.Threading.CancellationTokenSource Object

b) THREAD A: This CancellationTokenSource is given to the parallel task

c) THREAD B: The underlying method of the parallel task includes the type of CancellationTokenSource in its signature to take it over.


If a "cancel" button was pushed in THREAD A, then CancellationTokens method Cancel must be raised. This is done like this:
CancellationTokenSource.Token.Cancel();

The routine inside THREAD B (expecting while...wend loop for instance) is checking the CancellationTokenSource.Token.IsCancellationRequested = true
state and aborts its work in this case.

done!

shorter term of exception handling with the help of the Ternary operator

For example:

catch (System.ServiceModel.FaultException<AnyContract.ValidationError> ex)
            {
                Console.WriteLine(ex.Detail != null ? ex.Detail.Message : ex.InnerException != null ? ex.InnerException.Message : ex.Message);
            }

or

catch (Exception ex)
            {
                Console.WriteLine(ex.InnerException != null ? ex.InnerException.Message : ex.Message);
            }
