'Declaration Public Shared Function Combine ( _ a As Delegate, _ b As Delegate _ ) As Delegate
public static Delegate Combine( Delegate a, Delegate b )
The delegate whose invocation list comes first.
The delegate whose invocation list comes last.
A new delegate with an invocation list that concatenates the invocation lists of a and b in that order. Returns a if b is nulla null reference (Nothing in Visual Basic), returns b if a is a null reference, and returns a null reference if both a and b are null references.
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.
