Question

我有一个从C＃（WPF）应用程序以编程方式安装打印机驱动程序的指令。不得允许用户退出我的应用程序并从Windows安装。我已设法通过手动实现这一目标：

通过pnputil -i -a file.inf安装驱动程序。
（如果提升，这在PowerShell和命令提示符下都很有效。）
通过PowerShell添加打印机驱动程序。
通过PowerShell添加打印机端口。
通过PowerShell添加打印机。

如果我通过手动运行＃1将驱动程序添加到商店，我的代码效果很好。但无论出于何种原因我都无法得到ps或cmd从C＃运行相同的命令（成功）。它返回错误驱动程序不在商店。这是来自沙盒应用程序的代码。

{
    rs = RunspaceFactory.CreateRunspace();
    rs.Open();

    using (PowerShell ps = PowerShell.Create())
    {
        ps.AddScript(script);

        ps.Invoke();
        foreach (ErrorRecord err in ps.Streams.Error)
        {
            MessageBox.Show(err.ToString());
        }
    }

    // rs.Close();
}

}   // class MainWindow

有人可以向我解释我做错了吗？

cmd提示符确实运行（Windows要求我允许它进行更改），但它没有安装驱动程序。如果我从应用程序复制相同的字符串并粘贴到提升的命令提示符，它可以工作。任何帮助表示赞赏。

解决：

我将其更改为使用提升的powershell cmd：

No sequencer available for 'win32' platform.
