如何使用Powershell和自定义按钮最小化WPF窗口
您好我已经在WPF中开发了一个用户界面，我正在将该UI用于PowerShell，我想更改Titlebar颜色，因为我实施了一个Custome Templete并且它正在工作但我不知道如何处理最小化最大化和窗口关闭按钮的点击事件，
下面是我的代码。

是操作窗口
目前我的关闭，最大化和最小化按钮无法正常工作，请帮助我如何在Powershell中编写该事件？

您需要使用$Window.WindowState属性来说明表单是否应最小化，最大化或恢复正常。下面的代码显示了如何完成它。
#Minimize the Window
$MinimizeButton.Add_Click({
$Window.WindowState = 'Minimized'
})
$MaxRestoreButton.Add_Click({
If ($Window.WindowState -eq 'Normal') {
#Maximize the window
$Window.WindowState = 'Maximized'
} Else {
#Put window back to its normal size if maximized already
$Window.WindowState = 'Normal'
}
})
