VB.NET

PrivateSub TabControl1_DrawItem(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DrawItemEventArgs) Handles TabControl1.DrawItem
     'Me.TabControl1.DrawMode = TabDrawMode.OwnerDrawFixed ' 必须先改变模式(可将此句放在Load事件上)
    Dim tabArea As Rectangle
     Dim tabTextArea As RectangleF
    tabArea = TabControl1.GetTabRect(e.Index)
    tabTextArea = CType(TabControl1.GetTabRect(e.Index), RectangleF)

     Dim g As Graphics = e.Graphics
     Dim sf As StringFormat = New StringFormat()
    sf.LineAlignment = StringAlignment.Center
    sf.Alignment = StringAlignment.Center

     Dim font As Font = Me.TabControl1.Font
     Dim brush As SolidBrush = New SolidBrush(Color.Black)
    g.DrawString((CType(sender, TabControl)).TabPages(e.Index).Text, font, brush, tabTextArea, sf)
 End Sub

C#.NET

private void tabControl1_DrawItem(object sender, DrawItemEventArgs e)
{
    //this.tabControl1.DrawMode = TabDrawMode.OwnerDrawFixed; // 必须先改变模式(可将此句放在Load事件上)
    Rectangle tabArea;
    RectangleF tabTextArea;
    tabArea = tabControl1.GetTabRect(e.Index);
    tabTextArea = (RectangleF)tabControl1.GetTabRect(e.Index);
    Graphics g = e.Graphics;
    StringFormat sf = new StringFormat();
    sf.LineAlignment = StringAlignment.Center;
    sf.Alignment = StringAlignment.Center;
    Font font = this.tabControl1.Font;
    SolidBrush brush = new SolidBrush(Color.Black);
    g.DrawString(((TabControl)(sender)).TabPages[e.Index].Text, font, brush, tabTextArea, sf);
