我正在编写一个 powershell 脚本,它安装了各种驱动程序。
我的脚本工作正常,所以我想使用 WPF 添加一个 gui。首先,我使用 WPF 创建了一个 gui,没什么特别的,只是一个带有标签的窗口。
我想从我的安装脚本中更新这个标签。所以我创建了两个运行空间,一个创建并显示 WPF gui,另一个执行我的安装脚本。只要我使用的是 powershell 版本 3 或更高版本,它就可以正常工作。使用 powershell 2,我不得不在新的 Windows 7 安装中使用它,wpf 运行空间崩溃了。
我希望有一种方法可以使用 powershell 版本 2。
这是一个示例脚本,演示了我在做什么。
