Two delegates are considered not equal if they are of different types, or have different methods, different targets, or different invocation lists.

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

NoteImportant:

In the .NET Framework version 1.0 and 1.1, two delegates are 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 not equal if they have different sizes, if they are ordered differently, or if at least one element from one list represents a method or target that is different from that represented by its corresponding element in the other list.
