Winform 中tabcontrol 美化

需要对tabcontrol按照美工出的图进行美化

对tabpage页进行标题设置，首先对整个tabcontrol的DrawMode设置为OwnerDrawFixed，由于需要对标题宽度有要求，设置sizemode为fixed，可以对itemsize调整，设置标题的宽和高，然后进行写事件就能实现

 private void tb_DrawItem(object sender, DrawItemEventArgs e)
        {
            StringFormat sf = new StringFormat();

            #region 头背景
            sf.LineAlignment = StringAlignment.Center;
            sf.Alignment = StringAlignment.Center;
            Rectangle rec = tb.ClientRectangle;
            //获取背景图片，我的背景图片在项目资源文件中。
            Image backImage = Properties.Resources.pop_tab1_2;
            e.Graphics.DrawImage(backImage, 0, 2, tb.Width, tb.ItemSize.Height + 2);
            #endregion
            #region  设置选择的标签的背景
            if (e.Index == tb.SelectedIndex)
                e.Graphics.DrawImage(Properties.Resources.pop_tab1_1, e.Bounds.X, e.Bounds.Y, e.Bounds.Width, e.Bounds.Height);
            else
                e.Graphics.DrawImage(Properties.Resources.pop_tab1_2, e.Bounds.X, e.Bounds.Y, e.Bounds.Width, e.Bounds.Height);
            e.Graphics.DrawString(((TabControl)sender).TabPages[e.Index].Text,
            System.Windows.Forms.SystemInformation.MenuFont, new SolidBrush(Color.Black), e.Bounds, sf);
            #endregion
            #region 重写标签名
            ColorConverter colorConverter = new ColorConverter();
            Color cwhite = (Color)colorConverter.ConvertFromString("#2178ba");
            SolidBrush white = new SolidBrush(cwhite);
            Rectangle rect0 = tb.GetTabRect(0);
            StringFormat stringFormat = new StringFormat();
            stringFormat.Alignment = StringAlignment.Center;
            stringFormat.LineAlignment = StringAlignment.Center;

　　　　　　　e.Graphics.DrawString("申请单号", new Font("微软雅黑", 12), white, rect0, stringFormat);

           #endregion
        }
