MulticastDelegate.Equality(MulticastDelegate, MulticastDelegate) Operator

Definition

Determines whether two MulticastDelegate objects are equal.

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

Parameters

d1
MulticastDelegate

The left operand.

d2
MulticastDelegate

The right operand.

Returns

true if d1 and d2 have the same invocation lists; otherwise, false.

Exceptions

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 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.

The equivalent method for this operator is MulticastDelegate.Equals(Object)
