In C#, how can I halt the execution of an event from one of its bound delegates?

You could use something like HandledEventArgs (or use a similar concept), with this, when the event is handled, you set the 'handled' property and check this property in your other delegates.

I think I may have answered my own question.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
