You can do this

foreach(var cb in checkboxlist){
   if(cb is CheckBox && cb.isChecked)
   {
     //Your Custom code here
   }
}

Or you can point all of the Checkboxes at the same isChecked event. This is probably a cleaner option than the foreach but it really depends on how you need to put it in.

Edit

I will leave my answer up for comparison but the two that use CheckedIndices are way better solutions.

      if (checkedListBox1.CheckedIndices.Count > 0)
       {

        //Selected some items
       }
