Delegate chaining allows you to create a linked list of delegates such that when the delegate at the head of the list is called, all of the delegates in the chain are called. The System.Delegate class provides a few static methods to manage lists of delegates.

Delegate.Combine(), Delegate.Remove() & Delegate.RemoveAll()

• The result that comes out from chained invocation is the result of the last delegate.
• Any exception in chained invocation terminates the chained invocation process.
• You can also pass value by reference, but be aware that each delegate that uses the reference parameter will see the changes made by the previous delegate in the chain.
• Before invoking the delegate chain, you must cast the delegate back into the explicit delegate type.
