tabcontrol不给力，标题不能改解决方法。直接上源码，不注释。

            Rectangle tabArea1;            Rectangle tabArea2;            RectangleF tabTextArea1;            RectangleF tabTextArea2;            tabArea1 = tabControl1.GetTabRect(0);            tabArea2 = tabControl1.GetTabRect(1); ;            tabTextArea1 = (RectangleF)tabControl1.GetTabRect(0);            tabTextArea2 = (RectangleF)tabControl1.GetTabRect(1);            Graphics g = e.Graphics;            Pen p = new Pen(Color.Black);            Font font = new Font("宋体", 9.0f);            SolidBrush brush = new SolidBrush(Color.Silver);            e.Graphics.FillRectangle(brush, tabControl1.Bounds);

             brush = new SolidBrush(Color.LightGray);            e.Graphics.FillRectangle(brush, e.Bounds);            brush = new SolidBrush(Color.WhiteSmoke);            g.FillRectangle(brush, tabTextArea1);             g.FillRectangle(brush, tabTextArea2);            brush = new SolidBrush(Color.Black);            StringFormat sf = new StringFormat();

            sf.LineAlignment = StringAlignment.Center;            sf.Alignment = StringAlignment.Center;

            g.DrawString("  酒店管理  ", font, brush, tabTextArea1, sf);            g.DrawString("酒店区域管理", font, brush, tabTextArea2, sf);
