c# - How to manually invoke an event?

I have the following line in C#:

_timer.ElapsedTick += _somefunction1;
_timer.ElapsedTick += _somefunction2;
_timer.ElapsedTick += _somefunction3;

How to invoke all methods subscribed to _timer.ElapsedTick without specifying the _somefunction ? Somewhere along this pseudo-line

invoke(_timer.ElapsedTick);
See Question&Answers more detail:os

You can't invoke an event which is owned by another type. An event can only be invoked from the inside the class which declares it.
