Is there a way to know in VB.NET if a handler has been registered for an event?

Question

In C# I can test for this...

public event EventHandler Trigger;
protected void OnTrigger(EventArgs e)
{
    if (Trigger != null)
        Trigger(this, e);
}
         


        

Answer 1

I believe the syntax I use for this in VB.Net is:

Public Event Trigger As EventHandler


Friend Sub OnTrigger(ByVal e As EventArgs)
    If TriggerEvent IsNot Nothing Then
        RaiseEvent Trigger(Me, e)
    End If
End Sub

Even though TriggerEvent does not appear to be declared the compiler will understand it.It closer emulates the C# syntax. Also I have read somehere that the code with that handler asssigned check runs fater, but I cannot point to that at the moment, so youcan take or leave that.

I think that is the sytax, anyway. Please dont shoot me if it is not quite correct!
