我们在winform中给按钮设置个背景图片超级简单，是不？可是在wince下面就没那么简单了，下面我来介绍一种方式来实现ImageButton。

实现思路是重新写一个usercontrol就ok。具体的实现方式如下：

/IotButton是我们新控件的名字，具体的可以自己定义 public partial class IotButton : UserControl     {        public IotButton()        {            InitializeComponent();        }         Image backgroundImage;        bool pressed = false;         // Property for the background image to be drawn behind the button text.          public Image BackgroundImage        {            get            {                return this.backgroundImage;            }            set            {                this.backgroundImage = value;            }        }        // When the mouse button is pressed, set the "pressed" flag to true           // and invalidate the form to cause a repaint.  The .NET Compact Framework           // sets the mouse capture automatically.          protected override void OnMouseDown(MouseEventArgs e)        {            this.pressed = true;            this.Invalidate();            base.OnMouseDown(e);        }         // When the mouse is released, reset the "pressed" flag           // and invalidate to redraw the button in the unpressed state.          protected override void OnMouseUp(MouseEventArgs e)        {            this.pressed = false;            this.Invalidate();            base.OnMouseUp(e);        }         // Override the OnPaint method to draw the background image and the text.          protected override void OnPaint(PaintEventArgs e)        {            e.Graphics.FillRectangle(new SolidBrush(SystemColors.ActiveCaption), e.ClipRectangle);             if (this.backgroundImage != null)            {                ImageAttributes attr = new ImageAttributes();                attr.SetColorKey(Color.Magenta, Color.Magenta);                 if (this.pressed)                    e.Graphics.DrawImage(this.backgroundImage, this.ClientRectangle, 0, 0, this.backgroundImage.Width, this.backgroundImage.Height, GraphicsUnit.Pixel, attr);                else                    e.Graphics.DrawImage(this.backgroundImage, this.ClientRectangle, 0, 0, this.backgroundImage.Width, this.backgroundImage.Height, GraphicsUnit.Pixel, attr);             }             base.OnPaint(e);        }    }

 这里为什么要实现一个新的UserControl而不是基于Button呢？具体原因是这样的，因为Button中没有Paint事件，没有MouseUP MouseDown MouseMove等事件因此不能很好的实现，有图有证据哦？

看看我们自定义的按钮的事件和属性吧：

总结

上面的方式实现了在wince下自定义一个可以放image的控件，具体的不同我们可以对比上面的两图得到。希望对大家有帮助哦。
