Override GetItemCheckState() from a checklistbox

Question

Is there any way to override GetItemCheckState(i) from CheckedListBox? I'm trying to make a class to have a custom CheckedListBox that works the exact same, but when I call GetItemCheckState(i) instead of returning string Checked or Unchecked I want it to return bool true or false. Visual Studio tells me that the override modifier is not valid for this item, is there any way around this?

[Edit] I found a workaround, but I'm not sure if it will cause some sort of issue and I dunno if it's the most elegant solution, so almost same question still, there is a better workaround for this?

What I did:

public class ExCheckedListBox : CheckedListBox
    {

        public bool GetItemCheckState2(int index)
        {
            string aux = (this.GetItemCheckState(index)).ToString();
            if(aux == "Checked")
            {
                return true;
            }
            else if(aux == "Unchecked")
            {
                return false;
            }
            return false;
        }
    }

As LarsTech and Ben Voigt said, GetItemChecked(#) or GetItemCheckState(index) != CheckState.Unchecked; solves my issue.
