            /* Draw Item Text */
            g.DrawString(listBox1.Items[e.Index].ToString(), e.Font, new SolidBrush(Color.Black), e.Bounds, StringFormat.GenericDefault);

            e.DrawFocusRectangle();
        }

推荐答案

也许你没有在Listbox中设置DrawDode属性为OwnerDrawFixed或OwnerDrawVariable。

Maybe you didn't set in your listbox the DrawMode property to OwnerDrawFixed or OwnerDrawVariable.
