来源：http://topic.csdn.net/t/20050526/17/4038042.html

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);
