C#(winform)很多按钮同时更改贴图（Image）该如何处理?
RT winform 中
我这里有几十个按钮，如果要同时切换他们的状态（就是更改它们的贴图Imgae）,该怎么写代码？
难道真要像下面这样？能不能优化一下，主要从性能方面考虑，因为这样按钮有个很明显的刷新过程......
btn_ZhengFeng.Image = NoActivated;
btn_FuPai.Image = NoActivated;
btn_00LYan.Image = NoActivated;
btn_1LYan.Image = NoActivated;
btn_2LYan.Image = NoActivated;
btn_3LYan.Image = NoActivated;
btn_4LYan.Image = NoActivated;
btn_ZhaoMin.Image = NoActivated;
btn_JuanShang.Image = NoActivated;
btn_JuanXia.Image = NoActivated;
btn_00LLin.Image = NoActivated;
btn_1LLin.Image = NoActivated;
btn_2LLin.Image = NoActivated;
btn_3LLin.Image = NoActivated;
btn_4LLin.Image = NoActivated;
btn_ZiDongQiDong.Image = NoActivated;
