Is it possible to get which character of text is clicked on C# form?

Question

I am trying to get which of the * is clicked in text of label as in picture.

NOTE : Number of * is not known at first.User inputs it.So the position of mouse click is not useful.

Answer 1

Answer is :

X of first *'s location is known, equals = 10 .The asterisks are spaced equally,distance between two * is ~15 pixel .

When user clicks on one of asterisks , index of asterisks can be calculated as the code below

private void label4_MouseDoubleClick(object sender, MouseEventArgs e)
        {
            double t = (e.X - 10) / 15.0;
            int indexOfClickedAsterisk=(int)Math.Round(t) + 1;
        }
