C#自定义Button按钮控件

　　在实际项目开发中经常可以遇到.net自带控件并不一定可以满足需要，因此需要自定义开发一些新的控件，自定义控件的办法也有多种，可以自己绘制线条颜色图形等进行重绘，也可以采用已有的控件作为控件的一个组成部分从而组成新的控件，本例中使用后者这里做了一个简单的按钮控件，特意帖上来，如有不足之处请见谅！

  5 
  6         [Description("控件的默认图片")]
  7         public Image ImageDefault
  8         {
  9             get { return _imageDefault; }
 10             set 
 11             { 
 12                 _imageDefault = value;
 13                 label.Image = _imageDefault;
 14             }
 15         }
 16         /// <summary>

3.添加事件

1         /// <summary>
2         /// 鼠标单击事件
3         /// </summary>
4         public event EventHandler ButtonClick;

4.添加鼠标响应事件

 1  /// <summary>
 2         /// 鼠标单击事件
 3         /// </summary>
 4         /// <param name="sender"></param>
 5         /// <param name="e"></param>
 6         private void label_Click(object sender, EventArgs e)
 7         {
 8             if (ButtonClick != null)
 9             {
10                 ButtonClick(sender, e);
11             }
12         }
13

17         /// <param name="sender"></param>
18         /// <param name="e"></param>
19         private void label_MouseMove(object sender, MouseEventArgs e)
20         {
21             if (backColorMove != Color.Transparent)
22             {
23                 BackColorEX = backColorMove;
24             }
25             if (_imageMove != null)
26             {

41             }
42             if (_imageLeave != null)
43             {
