WPF如何封装一个可扩展的Window

前言

    WPF中Window相信大家都很熟悉，有时我们有一些自定义需求默认Window是无法满足的，比如在标题栏上放一些自己东西，这个时候我们就需要写一个自己的Window，实现起来也很简单，只要给Window设置一个WindowChrome.WindowChrome附加属性就可以实现，WindowChrome 可以让你自定义窗口的非工作区的外观和行为。非工作区就是窗口的标题栏和边框，通常由操作系统绘制和管理。WindowChrome 可以让你将 WPF 的内容扩展到非工作区，同时保留一些系统的功能和行为，比如调整大小，移动，最大化，最小化等。

一、示例代码

1.1 基本使用

<local:CustomWindow
    x:Class="CustomWindowDemo.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:local="clr-namespace:CustomWindowDemo"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    Title="Window1"
    Width="800"
    Height="450"
    Icon="/logo.png"
    mc:Ignorable="d">
    <Grid />
</local:CustomWindow>
