Raise an event with no arguments

Question

In VB.net I can declare and raise an event like this
Public Event SomeEvent()
Public Sub SomeMethod
RaiseEvent SomeEvent()
End Sub
I need to work out how to do this in c# however all of the examples of raising events include event handlers.  This won't work for me as I am raising this event over a COM interface, and so I can't send eventargs or non basic types through the interface
to the client application.

Answer 1

OK, Action doesn't work as I end up with the following error
An exception of type 'System.InvalidCastException' occurred in AdtakerInterfaceSampleCsharp.exe but was not handled in user code
Additional information: Unable to cast object of type 'System.__ComObject' to type 'System.Action'.
You asked how to raise an event with no arguments in C# and I gave you the solution for this. You could certainly use an Action to raise an event with no arguments as my sample code clearly demonstrates.
How to call your specific COM interface is a totally different topic.
