Challenge for an unknown WinForm element

[derk]

public void FunctionA(Object element)
{
 element.Items.Clear();
}

Example of use:

FunctionA(checkedListBox1);

Function FunctionA There will be arguments only checkedListBox and comboBoxboth elements have a method .Items.Clear();

How do you make it work?

[Demir]

public void FunctionA(IList aList)
{
  aList.Clear();
}

FunctionA(checkedListBox1.Items);
FunctionA(comboBox1.Items);

Update

What do you do if you add checkedListBox1 you need to do?

I default chekedbox.

No miracles.

if (aList is CheckedListBox.ObjectCollection)

{

((CheckedListBox.ObjectCollection)aList).Add(Text, true);

}

else

{

aList.Add(Text);

}
