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；
复制代码 代码如下:
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="/FirstFloor.ModernUI;component/Assets/ModernUI.xaml" />
<ResourceDictionary Source="/FirstFloor.ModernUI;component/Assets/ModernUI.Light.xaml"/>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
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）；
复制代码 代码如下:
<Label Margin="280,169,0,0" Style="{StaticResource BackGroundContentText}" x:Name="lblMainState" HorizontalAlignment="Left" VerticalAlignment="Top">正在启动:</Label>
<ProgressBar Margin="280,200,0,0" HorizontalAlignment="Left" VerticalAlignment="Top" Width="500" Minimum="0" x:Name="ProgressControlRealValue" Maximum="1" Value="0.1" Height="16" IsIndeterminate="False"/>
<Label Margin="280,212,0,0" Style="{StaticResource BackGroundContentText}" x:Name="lblProcess" HorizontalAlignment="Left" VerticalAlignment="Top">正在加载地图数据...</Label>
<ProgressBar Margin="280,250,0,0" HorizontalAlignment="Left" VerticalAlignment="Top" Minimum="0" x:Name="ProgressControl" Width="500" Maximum="2" Height="16" IsIndeterminate="True" />
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）；
