Can I reverse the order of a multicast delegate event?

Question

When you subscribe to an event in .NET, the subscription is added to a multicast delegate. When the event is fired, the delegates are called in the order they were subscribed.<

Controlling When and If a Delegate Fires Within a Multicast Delegate

The following method creates a multicast delegate called allInstances and then uses GetInvocationList to allow each delegate to be fired individually, in reverse order:

public static void InvokeInReverse()
{
    MyDelegate myDelegateInstance1 = new MyDelegate(TestInvoke.Method1);
    MyDelegate myDelegateInstance2 = new MyDelegate(TestInvoke.Method2);
    MyDelegate myDelegateInstance3 = new MyDelegate(TestInvoke.Method3);

    MyDelegate allInstances =
            myDelegateInstance1 +
            myDelegateInstance2 +
            myDelegateInstance3;

    Console.WriteLine("Fire delegates in reverse");
    Delegate[] delegateList = allInstances.GetInvocationList();
    for (int counter = delegateList.Length - 1; counter >= 0; counter--)
    {
        ((MyDelegate)delegateList[counter])();
    }
}
