为了界面友好,一般的操作时间较长时,都需要增加进度条提示。由于WPF自带的进度条其实不怎么好看,而且没啥视觉效果。后来,装VS2012时,发现安装过程中进度条效果不错,于是上网查了资料。学习了ModernUI(开源的),地址:https://github.com/firstfloorsoftware/mui。
后来,做了尝试写了个Demo,效果不错。另外,专门录制了tif文件,方便大家看到效果。废话不多说,先展示效果:
一、效果展示
A、VS2012安装界面图;
B、个人尝试Demo效果图:
二、实现说明
1、下载MUI相关代码或者dll文件;
2、工程中引入该dll,并引入其资源文件;
3、在需要显示进度条的页面,加入控件(其实还是WPF控件,只是MUI扩展了其样式而已);
4、后台实现,由于要根据情况更新进度文字及进度条的值。所以,这里用到了异步BackgroundWorker(具体可以网上查查相关资料);
