Pass Listbox to a function

[usamaalam]

I have developed a function in a class which takes argument of type ListControl. Now, from my form, I need to pass the reference of my listbox to the function and the function will then add items to listbox. How do I pass the reference of the listbox or combobox to the function.

The signature of the method is this :

public void Fill(ref ListControl thisList)

Thanks
