Anonymous delegates and event execution

by Brian Keating Tue, February 02 2010 15:18

A nice little trick to save you always checking for null when firing custom events
Initialize to anonymous delegate.
Ok.. we've an extra call in the invocation list so use judiciously

public event CompleteTaskExecutionHandler CompleteExecution = delegate { };

//or a sample using Lambdas

public event PropertyChangedEventHandler PropertyChanged = (s,p) => { };

 

 

private void Fire()
{
   this.CompleteExecution(...);
}
