Wpf 将变量绑定到Powershell中的combobox和textbox

我带着更多的问题来找你

我构建了一个简单的GUI来创建打印机或更改打印服务器上的驱动程序。但是，当我点击RUN按钮时，它不会使任何事情发生，只会弹出操作成功的消息。有人能帮我检查一下代码，告诉我我做错了什么吗

我测试了你的代码，并修改了这行代码，以向制作人展示它的工作原理。为什么说变量没有绑定

[System.Windows.MessageBox]::Show('Operation completed!' + $maker)

此外，还应进行检查

if ($RadioCreate.IsChecked -eq $true){

检查我的更新答案，并让我知道是否有帮助或任何问题。当我按下运行按钮时，程序不会执行任何操作，甚至不会启动创建打印队列的过程。我已经挣扎了很长一段时间了，老实说，我不知道我还能做些什么来让它工作。它正在工作，但只有创建部分：）我会找出为什么其他部分不工作。现在我需要添加更多的MessageBox，以使其与用户更具交互性。非常感谢@很好，我的回答有用吗？
