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。

$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()
