if I understand your question right :

What you need is the method GetItemCheckState.

Usage as follows:

Try This :

  foreach (var item in listBox1.Items)
        {
            for (int i = 0; i < checkedListBox1.Items.Count; i++)
            {
                checkedListBox1.SetItemChecked(i, false);//First uncheck the old value!
                                                         //
                for (int x = 0; x < listBox1.Items.Count; x++)
                {
                    if (checkedListBox1.Items[i].ToString() == listBox1.Items[x].ToString())
                    {
                        //Check only if they match! 
                        checkedListBox1.SetItemChecked(i, true);
                    }
                }
            }


        }
