wpf 我想使用一个循环来创建基于PowerShell中XML窗口的所有命名方面的变量

请注意，我并不是一个有经验的程序员，我要去大学的IT和什么我没有在课堂上学习，我从谷歌和StackOverflow刮
我正在使用GUI创建一个PowerShell脚本，这既是一个挑战/练习，也是一个工具，可以帮助我完成兼职IT映像工作。我已经完成了所有内容的XML部分，现在我正在处理实际的逻辑，以给予窗口功能。
其中一部分是将所有命名的文本框/单选按钮分配给PowerShell中的变量，如果你像这样硬编码变量分配，这并不难：$radioButton = $window.FindName("radioButton")
然而，我有相当数量的文本框/单选按钮，我想操作，虽然我可以坐下来硬编码所有这些（我可能应该，因为这些都不会改变），我想做一个循环，遍历窗口中命名的所有内容，并基于它创建一个变量，主要是为了挑战，学习，因为它看起来更干净。
可能需要注意的是，我没有导入.xaml文件，它存在于PS脚本中，因此它不需要指向.xaml文件。
整个脚本本身，现在还没有完成，因为我试图创建的循环不起作用，这意味着变量没有被赋值：

$Null = $window.ShowDialog()

我试图让它工作的代码是：

$xaml.SelectNodes("//*[@Name]") | ForEach-Object{
    try{
        Set-Variable -Name "var_$($_.Name)" -Value $window.FindName($_.Name) -ErrorAction Stop
    }

    }
}

我不知道为什么这不起作用，或者我做错了什么。如果你能帮忙的话，我将不胜感激。

$xaml.SelectNodes("//*[@Name]")
不起作用，因为输入XAML文档中的Name属性是 * 命名空间限定的 *（x:Name）
为了通过传递给.SelectNodes()的查询来查询这些属性，您需要：

传递一个 namespace manager 对象作为第二个参数，其中与输入文档中相同的命名空间 URI Map到 prefix（也可以是x，但不是必须是）。
请在SQL查询中使用该前缀限定属性引用。

把它拼出来：

# Create a namespace manager for the input document.
$nsMgr = [System.Xml.XmlNamespaceManager]::new($xaml.NameTable)

# Add the relevant URI for the Name attributes, using a self-chosen
# prefix that may be but needn't be the same as in the input document.
$nsMgr.AddNamespace('x', 'http://schemas.microsoft.com/winfx/2006/xaml')

# Use the self-chosen prefix in the XPath query.
$xaml.SelectNodes("//*[@x:Name]", $nsMgr) |
  ForEach-Object{
    # Create a var_* variable for every control in the window, named for that control.
    Set-Variable -Name "var_$($_.Name)" -Value $window.FindName($_.Name)
  }
