tabcontrol中的侧对齐选项卡

Question

由于我是C＃初学者，我不知道在我的情况下该做什么。我想要一个侧面对齐的标签控件，所以我发现了这个：

现在标签页名称根本没有显示。我如何“画”他们？我希望有一个人可以帮助我。 DrawItem方法：

 private void tabControl1_DrawItem(object sender, DrawItemEventArgs e)
    {
        Graphics g = e.Graphics;
        Brush _textBrush;

        // Get the item from the collection.
        TabPage _tabPage = tabControl1.TabPages[e.Index];

        // Get the real bounds for the tab rectangle.
        Rectangle _tabBounds = tabControl1.GetTabRect(e.Index);

        if (e.State == DrawItemState.Selected)
        {

            // Draw a different background color, and don't paint a focus rectangle.
            _textBrush = new SolidBrush(Color.Red);
            g.FillRectangle(Brushes.Gray, e.Bounds);
        }
        else
        {
            _textBrush = new System.Drawing.SolidBrush(e.ForeColor);
            e.DrawBackground();
        }

        // Use our own font.
        Font _tabFont = new Font("Arial", (float)10.0, FontStyle.Bold, GraphicsUnit.Pixel);

        // Draw string. Center the text.
        StringFormat _stringFlags = new StringFormat();
        _stringFlags.Alignment = StringAlignment.Center;
        _stringFlags.LineAlignment = StringAlignment.Center;
        g.DrawString(_tabPage.Text, _tabFont, _textBrush, _tabBounds, new StringFormat(_stringFlags));
    }
