本文主要展示如何创建WPF窗口样式，目前窗口未做放大和缩小功能，只做关闭。

窗口基类创建

<base:WpfWindowBase x:Class="TJS.Library.AnalysisRegionModule.Views.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

Style="{StaticResource WinStyle}"

Title="Window1" Height="450" Width="800" Icon="/TJS.Library.AnalysisRegionModule;component/Images/fenxi.png">
