C#重绘TabControl的Tabpage标签，添加图片及关闭按钮

以下就是C#重绘TabControl控件的源码:效果如同所示：

using System.Linq; 
using System.Text; 
using System.Windows.Forms; 

namespace WindowsFormsApplication1.june 
{ 
    public partial class TabTest : Form 
    { 
        public TabTest() 
        { 
            InitializeComponent(); 
        } 

        private void TabTest_Load(object sender, EventArgs e) 
        { 
            //清空控件 
            //this.MainTabControl.TabPages.Clear(); 
            //绘制的方式OwnerDrawFixed表示由窗体绘制大小也一样 
            this.MainTabControl.DrawMode = TabDrawMode.OwnerDrawFixed; 
            this.MainTabControl.Padding = new System.Drawing.Point(CLOSE_SIZE, CLOSE_SIZE); 
            this.MainTabControl.DrawItem += new DrawItemEventHandler(this.MainTabControl_DrawItem); 
            this.MainTabControl.MouseDown += new System.Windows.Forms.MouseEventHandler(this.MainTabControl_MouseDown); 
        } 

        const int CLOSE_SIZE = 15; 
        //tabPage标签图片 
        Bitmap image = new Bitmap("E:\\ico_close.gif"); 

        //绘制“Ｘ”号即关闭按钮 
        private void MainTabControl_DrawItem(object sender, DrawItemEventArgs e) 
        { 
            try
            { 
                Rectangle myTabRect = this.MainTabControl.GetTabRect(e.Index); 

                //先添加TabPage属性    
                e.Graphics.DrawString(this.MainTabControl.TabPages[e.Index].Text,
this.Font,SystemBrushes.ControlText, myTabRect.X + 2, myTabRect.Y + 2); 
                //再画一个矩形框 
                using (Pen p = new Pen(Color.White)) 
                { 
                    myTabRect.Offset(myTabRect.Width - (CLOSE_SIZE + 3), 2); 
                    myTabRect.Width = CLOSE_SIZE; 
                    myTabRect.Height = CLOSE_SIZE; 
                    e.Graphics.DrawRectangle(p, myTabRect); 
                } 

                //填充矩形框 
                Color recColor = e.State == DrawItemState.Selected 
                          ? Color.White : Color.White; 
                using (Brush b = new SolidBrush(recColor)) 
                { 
                    e.Graphics.FillRectangle(b, myTabRect); 
                } 

                //画关闭符号 
                using (Pen objpen = new Pen(Color.Black)) 
                { 
                    ////============================================= 
                    //自己画X 
                    ////"\"线 
                    //Point p1 = new Point(myTabRect.X + 3, myTabRect.Y + 3); 
                    //Point p2 = new Point(myTabRect.X + myTabRect.Width - 3, myTabRect.Y + myTabRect.Height - 3); 
                    //e.Graphics.DrawLine(objpen, p1, p2); 
                    ////"/"线 
                    //Point p3 = new Point(myTabRect.X + 3, myTabRect.Y + myTabRect.Height - 3); 
                    //Point p4 = new Point(myTabRect.X + myTabRect.Width - 3, myTabRect.Y + 3); 
                    //e.Graphics.DrawLine(objpen, p3, p4); 

                    ////============================================= 
                    //使用图片 
                    Bitmap bt = new Bitmap(image); 
                    Point p5 = new Point(myTabRect.X, 4); 
                    e.Graphics.DrawImage(bt, p5); 
                    //e.Graphics.DrawString(this.MainTabControl.TabPages[e.Index].Text, this.Font, objpen.Brush, p5); 
                } 
                e.Graphics.Dispose(); 
            } 
            catch (Exception) 
            { } 
        } 

        //关闭按钮功能 
        private void MainTabControl_MouseDown(object sender, MouseEventArgs e) 
        { 
            if (e.Button == MouseButtons.Left) 
            { 
                int x = e.X, y = e.Y; 
                //计算关闭区域    
                Rectangle myTabRect = this.MainTabControl.GetTabRect(this.MainTabControl.SelectedIndex); 

                myTabRect.Offset(myTabRect.Width - (CLOSE_SIZE + 3), 2); 
                myTabRect.Width = CLOSE_SIZE; 
                myTabRect.Height = CLOSE_SIZE; 

                //如果鼠标在区域内就关闭选项卡    
                bool isClose = x > myTabRect.X && x < myTabRect.Right && y > 
myTabRect.Y && y < myTabRect.Bottom; 
                if (isClose == true) 
                { 
                    this.MainTabControl.TabPages.Remove(this.MainTabControl.SelectedTab); 
                } 
            } 
        } 
    } 
}

可以加一个imageList，然后设置tabControl的imageList属性，再设置各个tab的ImageIndex或ImageKey属性，即可，只不过这样图标会在文本的左侧。如同所示：

还有办法是重写了个tabControl，继承一个tabControl，然后建一个资源文件夹，在里面添加你需要的图片，在OnDrawItem时你重绘一下就好了，然后判断OnMouseEnter事件时修改矩形框的图片（从资源文件夹里获取）！可以参考示例http://www.codeproject.com/KB/dotnet/CustomTabControl.aspx
