MulticastDelegate.Inequality Operator (MulticastDelegate, MulticastDelegate)


Determines whether two MulticastDelegate objects are not equal.

Namespace:   System
Assembly:  mscorlib (in mscorlib.dll)

public static bool operator !=(
	MulticastDelegate d1,
	MulticastDelegate d2


Type: System.MulticastDelegate

The left operand.

Type: System.MulticastDelegate

The right operand.

Return Value

Type: System.Boolean

true if d1 and d2 do not have the same invocation lists; otherwise, false.

Exception Condition

Cannot create an instance of an abstract class, or this member was invoked with a late-binding mechanism.

Two delegates are equal if they are not null and are of exactly the same type, their invocation lists contain the same number of elements, and every element in the invocation list of the first delegate is equal to the corresponding element in the invocation list of the second delegate.

Two invocation list elements are equal if they invoke the same instance method on the same target instance, or they invoke the same static method.


when invoked late-bound through mechanisms such as Type.InvokeMember. Associated enumeration: ReflectionPermissionFlag.MemberAccess
