Determines whether two MulticastDelegate objects are equal.

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

Syntax

'Declaration
Public Shared Operator = ( _
    d1 As MulticastDelegate, _
    d2 As MulticastDelegate _
) As Boolean

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

Parameters

Return Value

Type: System.Boolean
true if d1 and d2 have the same invocation lists; otherwise, false.

Exceptions

Exception Condition
MemberAccessException

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

Remarks

Two delegates are equal if they are not nulla null reference (Nothing in Visual Basic) 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.
