You may do a cast:

typedef void (*VoidFunc)(void);

	VoidFunc my_func = (VoidFunc)myMethod;
	my_func ();

but be aware that this way is not supported (since it doesn't take care
of exceptions and the unmanaged->managed transition) so it shouldn't be
used in production code.
The correct way is to call (if you want to just ignore exceptions):

	mono_runtime_invoke (someMethod, NULL, NULL, NULL);
