I currently have the following code -

Button btn = new Button();
bool blnEventHandlerSet = false;

...

btn.Click += new EventHandler( btn_Click );
blnEventHandlerSet = true;

...

btn.Click -= new EventHandler( btn_Click );
blnEventHandlerSet = false;

...

so that the 'blnEventHandlerSet' variable is here to indicate if event
handler has been assigned.

Is there a way to determine if a button's click event has at least one
handler by using reflection?

thank you.
