把button的背景设为该图片，borderwidth为0，样式为flat，就可以了。
至于拖动，一般用类，没有一个一个按钮的编写拖动代码。下面是一个拖动类。
C#控件拖动和缩放类
这几天，因为项目需要，要对窗体上的控件进行拖动并对大小进行缩放，于是封装了该类：

具体的调用方式如：
DragResizeControl.BindControl(this.button1);
就像普通的Windows Forms应用中注册控件的事件代码一样，只要绑定了控件后，就可以很方便地实现对控件的拖动与缩放了。
用金山系统急救箱扫下就可以了
很简单，卸载它，从新安装，或者更新一下也应该可以，但卸载之前必须把它的安装程序或压缩包下载下来，不然然没有浏览器打不开网络，再不临时安个别的360啥的，你的明白！
是恶评插件
可以用360清除
你下载完还得安装啊，放个快捷图标就能用的么？
这个用杀毒没用。淘宝的图标不是病毒，人家是广告木马，得用360系统急救箱。
