C#做的.net水晶按纽控件

zkkpkk

我这几天呕心厉血做的.net水晶按纽控件，发上来给正在用.net平台的同僚们使用
用到了GDI+绘图二级缓存技术，小弟这几天初涉GDI+
希望有GDI图形编程这方面资料的同学传一下

新建windows应用程序，控件栏里由击鼠标，选添加/移除项，在出来的筐筐里点右下角的浏览，然后选择压出来的dll文件即可

这个也不错!

帮你找到几个BUG~~~~改变窗体背景色后按钮背景色还是白色,不会透明,,按钮内的字体大小不能更改
将按钮高度拖小后会出先内存不足的错误提示,其实偶机器一点都不卡~~

谢谢，这些问题我也发现了，字体不能改，换色就漏馅，以后还会有改进的，至于内存的那个我倒是没发现
