1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55

using System.Drawing; using System.Windows.Forms;   namespace Demo.UC {     public class KKTab : TabControl     {         private int IconWOrH = 16;         private Image icon = null;           public KKTab()             : base()         {             this.DrawMode = TabDrawMode.OwnerDrawFixed;               icon = Demo.Properties.Resources.close;             IconWOrH = icon.Width;             IconWOrH = icon.Height;         }           protected override void OnDrawItem(DrawItemEventArgs e)         {             Graphics g = e.Graphics;             Rectangle r = GetTabRect(e.Index);             if (e.Index == this.SelectedIndex)    //当前选中的Tab页，设置不同的样式以示选中             {                 Brush selected_color = Brushes.SteelBlue; //选中的项的背景色                 g.FillRectangle(selected_color, r); //改变选项卡标签的背景色                 string title = this.TabPages[e.Index].Text;                 g.DrawString(title, this.Font, new SolidBrush(Color.Black), new PointF(r.X , r.Y + 5));//PointF选项卡标题的位置                 r.Offset(r.Width - IconWOrH, 2);                 g.DrawImage(icon, new Point(r.X, r.Y));//选项卡上的图标的位置 fntTab = new System.Drawing.Font(e.Font, FontStyle.Bold);             }             else//非选中的             {                 Brush selected_color = Brushes.AliceBlue; //选中的项的背景色                 g.FillRectangle(selected_color, r); //改变选项卡标签的背景色                 string title = this.TabPages[e.Index].Text+"  ";                 g.DrawString(title, this.Font, new SolidBrush(Color.Black), new PointF(r.X , r.Y + 5));//PointF选项卡标题的位置                 r.Offset(r.Width - IconWOrH, 2);                 g.DrawImage(icon, new Point(r.X, r.Y));//选项卡上的图标的位置             }         }           protected override void OnMouseClick(MouseEventArgs e)         {             Point point = e.Location;             Rectangle r = GetTabRect(this.SelectedIndex);             r.Offset(r.Width - IconWOrH - 3, 2);             r.Width = IconWOrH;             r.Height = IconWOrH;             if (r.Contains(point)) this.TabPages.RemoveAt(this.SelectedIndex);         }     } }

注意：使用方式：界面加载需处理TabPage Text属性

?

1 2 3 4

foreach (TabPage item in this.kkTab1.TabPages)            {                item.Text = item.Text + "  ";            }

运行效果如下：
