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！

Button按钮控件设计

1.添加一个用户自定义控件ButtonEX

按钮组成：lable标签一个,Dock设置为填充

2.添加控件属性

  /// <summary>
         /// 控件的默认图片
         /// </summary>
         private Image _imageDefault = null;

         [Description("控件的默认图片")]
         public Image ImageDefault
         {
             get { return _imageDefault; }
             set
             {
                 _imageDefault = value;
                 label.Image = _imageDefault;
             }
         }
         /// <summary>
         /// 光标移动到控件上方显示的图片
         /// </summary>
         private Image _imageMove = null;
         [Description("光标移动到控件上方显示的图片")]
         public Image ImageMove
         {
             get { return _imageMove; }
             set { _imageMove = value; }
         }
         /// <summary>
         /// 光标离开控件显示的图片
         /// </summary>
         private Image _imageLeave = null;
         [Description("光标离开控件显示的图片")]
         public Image ImageLeave
         {
             get { return _imageLeave; }
             set { _imageLeave = value; }
         }
         /// <summary>
         /// 控件的背景色
         /// </summary>
         private Color _backColorEX = Color.Transparent;

         [Description("控件的背景色")]
         public Color BackColorEX
         {
             get { return _backColorEX; }
             set
             {
                 _backColorEX = value;
                 label.BackColor = _backColorEX;
             }
         }

         /// <summary>
         /// 鼠标移动到控件上方显示的颜色
         /// </summary>
         private Color backColorMove = Color.Transparent;
         [Description("鼠标移动到控件上方显示的颜色")]
         public Color BackColorMove
         {
             get { return backColorMove; }
             set { backColorMove = value; }
         }
         /// <summary>
         /// 鼠标离开控件显示的背景色
         /// </summary>
         private Color backColorLeave = Color.Transparent;
         [Description("鼠标离开控件显示的背景色")]
         public Color BackColorLeave
         {
             get { return backColorLeave; }
             set { backColorLeave = value; }
         }
         /// <summary>
         /// 控件的文字显示
         /// </summary>
         private string textEX = "";
         [Description("显示的文字")]
         public string TextEX
         {
             get { return textEX; }
             set
             {
                 textEX = value;
                 label.Text = textEX;
             }
         }
         /// <summary>
         /// 文字的颜色
         /// </summary>
         private Color textColor = Color.Black;
         [Description("文字的颜色")]
         public Color TextColor
         {
             get { return textColor; }
             set
             {
                 textColor = value;
                 label.ForeColor = textColor;
             }
         }
         /// <summary>
         /// 用于显示文本的字体
         /// </summary>
         private Font fontM = new System.Drawing.Font("宋体", 12F, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, ((byte)()));
         [Description("用于显示文本的字体")]
         public Font FontM
         {
             get { return fontM; }
             set
             {
                 fontM = value;
                 label.Font = fontM;
             }
         }
         

3.添加事件

         /// <summary>
         /// 鼠标单击事件
         /// </summary>
         public event EventHandler ButtonClick;    

4.添加鼠标响应事件

  /// <summary>
         /// 鼠标单击事件
         /// </summary>
         /// <param name="sender"></param>
         /// <param name="e"></param>
         private void label_Click(object sender, EventArgs e)
         {
             if (ButtonClick != null)
             {
                 ButtonClick(sender, e);
             }
         }

         /// <summary>
         /// 鼠标移动到控件上显示的背景色和背景图
         /// </summary>
         /// <param name="sender"></param>
         /// <param name="e"></param>
         private void label_MouseMove(object sender, MouseEventArgs e)
         {
             if (backColorMove != Color.Transparent)
             {
                 BackColorEX = backColorMove;
             }
             if (_imageMove != null)
             {
                 _imageDefault = _imageMove;
             }
         }

         /// <summary>
         /// 鼠标离开控件后显示的背景色和背景图
         /// </summary>
         /// <param name="sender"></param>
         /// <param name="e"></param>
         private void label_MouseLeave(object sender, EventArgs e)
         {
             if (backColorLeave != Color.Transparent)
             {
                 BackColorEX = backColorLeave;
             }
             if (_imageLeave != null)
             {
                 _imageDefault = _imageLeave;
             }
         }
