ComVisibleAttribute(true) public static function Combine ( ... delegates : Delegate ) : Delegate
The array of delegates to combine.
Return ValueA new delegate with an invocation list that concatenates the invocation lists of the delegates in the delegates array. Returns a null reference (Nothing in Visual Basic) if delegates is a null reference (Nothing in Visual Basic), if delegates contains zero elements, or if every entry in delegates is a null reference (Nothing in Visual Basic).
Not all the non-null entries in delegates are instances of the same delegate type.
If the delegates array contains entries that are a null reference (Nothing in Visual Basic), those entries are ignored.
The invocation list can contain duplicate entries; that is, entries that refer to the same method on the same object.
Combine is useful for creating event handlers that call multiple methods each time an event occurs.
