Question

我尝试使用powershell（xml）创建wpf网格并将其固定到任务栏没有成功

这是代码：

$IP = ((ipconfig) -match "IPv4").split(":")[1].trim()
# Add xml
$xmlcontent = '<Window
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Name="window" WindowStyle="None" Height="40" Width="250"
ResizeMode="NoResize" ShowInTaskbar="false">
<Window.TaskbarItemInfo>
        <TaskbarItemInfo>
            <TaskbarItemInfo.ProgressValue></TaskbarItemInfo.ProgressValue>
        </TaskbarItemInfo>
    </Window.TaskbarItemInfo>
<Grid Name="grid" Height="40" Width="249" Background="#0f1317" >
    <Label Name="label" HorizontalContentAlignment="Center" VerticalContentAlignment="Center" Content="info" Foreground="White" FontSize="15" FontFamily="ariel"/>
</Grid>
</Window>'

# "#0f1317" - Background Color Server
# "#13181e" - Background color Client

# Add the required assemblies 
Add-Type -AssemblyName PresentationFramework,System.Windows.Forms

# Add a super simple form that contains a just with text within a grid
[xml]$xaml =  $xmlcontent.Replace("info","$env:COMPUTERNAME - $IP")

# Turn the xaml into a form
$script:window = [Windows.Markup.XamlReader]::Load((New-Object System.Xml.XmlNodeReader $xaml))
$xaml.SelectNodes("//*[@Name]") | ForEach-Object { Set-Variable -Name ($_.Name) -Value $window.FindName($_.Name) -Scope Script }

# Double click the window
$window.Add_MouseDoubleClick({
    $window.Close() 
})


$window.Left = $([System.Windows.SystemParameters]::WorkArea.Width-503)
$window.Top = $([System.Windows.SystemParameters]::WorkArea.Height-0)
$window.Topmost = $true
$window.Focusable = $true
$window.ShowDialog() | Out-Null

预期：在任务栏上显示wpf网格，其中包含机器名称和IP地址
实际结果：错误

使用“ 1”参数调用“ Load”的异常：“ Set属性 'System.Windows.Shell.TaskbarItemInfo.ProgressValue'引发了例外。“在行：28 char：1 + $ script：window = [Windows.Markup.XamlReader] :: Load（（New-Object System ... + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~~~ + CategoryInfo：未指定：（:) []，MethodInvocationException + FullyQualifiedErrorId：XamlParseException使用“ 0”参数调用“ ShowDialog”的异常：“无法设置可见性或调用窗口后的Show，ShowDialog或WindowInteropHelper.EnsureHandle 已关闭。“在线：41 char：1 + $ window.ShowDialog（）|空空 + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo：未指定：（:) []，MethodInvocationException + FullyQualifiedErrorId：InvalidOperationException

使用XML PowerShell将WPF网格固定到任务栏
