Invoke a method when object added to generic collection?

Hello,

 I have a generic collection class that looks something like this:

public class SignalEventList : List<SignalEvent>
{}

Whenever I add a new SignalEvent to a SignalEventList I want to perform a calculation:

public class SignalEventList : List<SignalEvent>
{
   List<double> results = new List<double>;

    private void doCalculation()
    {
         foreach(SignalEvent se in this) { results.Add(doCalculation());}
    }
}


except, I am really sick of calling "doCalculation()" from client code. I get two lines: 1.) the actual Add(), 2.) the annoying call to doCalculation(). I want the client to be completely ignorant of the call to doCalculation(). So, what I want is the client to Add(SignalEvent) and then doCalculation() occurs behind the scenes.

In perl, I might do this with a Tie variable. Any ideas for C#?

Many thanks, please let me know if you need more clarification.Start Free Trial
