Assembly:  mscorlib (in mscorlib.dll)

public override bool Equals(
	Object obj
)

Parameters

obj
Type: System.Object

The object to compare with the current delegate.

Return Value

Type: System.Boolean
true if obj and the current delegate have the same targets, methods, and invocation list; otherwise, false.

ExceptionCondition
MemberAccessException

The caller does not have access to the method represented by the delegate (for example, if the method is private).

If the two delegates are not of the same type, they are not considered equal.

Important noteImportant

In the .NET Framework version 1.0 and 1.1, two delegates were considered equal if their targets, methods, and invocation list were equal, even if the delegates were of different types.

The methods and targets are compared for equality as follows:

  • If the two methods being compared are both static and are the same method on the same class, the methods are considered equal and the targets are also considered equal.

  • If the two methods being compared are instance methods and are the same method on the same object, the methods are considered equal and the targets are also considered equal.

  • Otherwise, the methods are not considered to be equal and the targets are also not considered to be equal.

Two invocation lists are considered identical only if they have the same order and the corresponding elements from the two lists represent the same method and target.
