Calling MDI Parent Function

[LLM]

I found

DirectCast(Me.M diParent, FormMdiParent). MyMethodInFormM diParent()

as an exabple of how to call a function in the parent from the child. I can't for the life of me figure this out in c#. Can anyone help?

All my Function does is hide items on the toolbar. The function returns nothing (i.e. void).
