Powershell使用WPF技术实现弹窗提示实例

WPF （Windows Presentation Foundation）技术能让你创建窗口和对话框。它的优势是在窗体设计时能与代码分开。

这里有个简单的显示弹出消息练习。这个消息是定义在XAML代码中它的实现类似HTML（但是请区分大小写）。你能轻松的调整字体大小，内容，颜色等等。不需要嵌入任何代码。
复制代码代码如下:
$xaml = @"
<Window
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation">

<Border BorderThickness="20" BorderBrush="Yellow" CornerRadius="9" Background="Red">
  <StackPanel>
   <Label FontSize="50" FontFamily="Stencil" Background="Red" Foreground="White" BorderThickness="0">
    System will be rebooted in 15 minutes！
   </Label>

   <Label HorizontalAlignment="Center" FontSize="15" FontFamily="Consolas" Background="Red" Foreground="White" BorderThickness="0">
    Worried about losing data？ Talk to your friendly help desk representative and freely share your concerns！
   </Label>
  </StackPanel>
</Border>
</Window>
"@

$reader = [System.XML.XMLReader]::Create（[System.IO.StringReader] $xaml）
$window = [System.Windows.Markup.XAMLReader]::Load（$reader）
$Window.AllowsTransparency = $True
$window.SizeToContent = "WidthAndHeight"
$window.ResizeMode = "NoResize"
$Window.Opacity = .7
$window.Topmost = $true
$window.WindowStartupLocation = "CenterScreen"
$window.WindowStyle = "None"
# show message for 5 seconds:
$null = $window.Show（）
Start-Sleep -Seconds 5
$window.Close（）
