In vb I can do that
sub SetFocusControl(byref ctl as object) ctl.Focus end sub
in c# the compiler complaint that object doesn't have a Focus method
void SetFocusControl(ref object ctl) { ctl.Focus(); }
how can I do the same in c#?

Could you not just call the Focus method directly?
ctl.Focus();
If you don't know the type or if it has a Focus method you could do this.
Void SetFocusControl(Control ctl.
Instead of using object, use the type that has the Focus method.

So you can construct another object of the same class without knowing what the original class's object is - this can make for some really neat compact factory pattern.

If there is no import of the interface in any of the calling code, you can be reasonably confident that your refactoring will work as planned.
