Anonymous delegates and event execution
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(...);
}
