如何使用powershell为passwordBox[WPF]的PasswordRevealMode设置属性

我想知道如何使用复选框在带有powershell（使用WPF）的密码框中显示或隐藏密码。我找到了很多关于c#的例子，但我无法让它与powershell一起工作。如何将powershell中的paswordrevealmode属性设置为“隐藏”或“可见”

在c#中，这是这样做的：

    private void CheckBox_Changed(object sender, RoutedEventArgs e)
{
    if (revealModeCheckBox.IsChecked == true)
    {
        passwordBox1.PasswordRevealMode = PasswordRevealMode.Visible;
    }
    else
    {
        passwordBox1.PasswordRevealMode = PasswordRevealMode.Hidden;
    }
}

我知道我在这里遗漏了一些东西，我仍在使用powershell学习wpf:）

我使用的代码如下所示：

function Get-Info () {
[void][System.Reflection.Assembly]::LoadWithPartialName('presentationframework')
[xml]$XAML = @'

在powershell中设置此属性似乎不是正确的方法。。我在执行此操作时出现以下错误：

The property 'PasswordRevealMode' cannot be found on this object. Verify that the property exists and can be set.

实际的GUI如下所示：

    private void CheckBox_Changed(object sender, RoutedEventArgs e)
{
    if (revealModeCheckBox.IsChecked == true)
    {
        passwordBox1.PasswordRevealMode = PasswordRevealMode.Visible;
    }
    else
    {
        passwordBox1.PasswordRevealMode = PasswordRevealMode.Hidden;
    }
}

我发现了一种使用弹出消息来显示密码的方法，但我尝试使用密码框来显示密码，如下所述：

提前谢谢

因此，我查看了文档，默认情况下，passwordbox控件上应该有一个允许显示的按钮。如果你的没有，那么还有别的事情在发生。首先，您是否在代码中显式导入了Windows.UI.Xaml.Controls？我不这么认为。。我认为它是presentationframework的一部分，那么如何导入它？@jiciftw我认为这是不可能的，因为WPF PasswordBox中没有PasswordRevealMode属性。该属性似乎适用于通用Windows平台应用程序，而不是Powershell GUI。当我尝试强制此属性时，它会说，

System.Windows.Controls.PasswordBox.PasswordRevealMode

未知。对于Windows窗体中的常规文本框，您可以使用字符来屏蔽实际输入字符以获得屏蔽密码输入。使用密码框对安全性不是更好吗？密码以securestring的形式给出，这与使用文本框然后将其转换为安全字符串有区别吗？
