C# event with custom arguments

I want to have an event that takes an enum only as the argument. For example

public enum MyEvents{
   Event1
}

// how do I declare this to take enum MyEvents as argument
public static event EventHandler EventTriggered;

public static void Trigger(MyEvent event )
{
    if (EventTriggered != null)
    {
        EventTriggered(event);
    }
}
