以管理员身份使用C＃的参数运行CMD

我想以管理员身份运行 cmd.exe ，参数来自 C＃，以防止出现 UAC 弹出式窗口。这是必要的，以便将其用作自动安装过程。我传递的命令只是安装文件（.exe）和 / q 安静安装的路径。

I want to run cmd.exe as administrator with arguments from C# in order to prevent a UAC popup. This is necessary in order to use it as an automated installation process. The command I am passing in is simply a path to installation file (.exe) with /q for quiet installation.

当我运行这个代码，有一个CMD弹出窗口，但它运行就像没有执行任何东西。

When I run this code, there is a CMD popup, but it runs as if it didn't execute anything.

public static string ExecuteCommandAsAdmin(string command)
{

    ProcessStartInfo procStartInfo = new ProcessStartInfo()
    {
        RedirectStandardError = true,
        RedirectStandardOutput = true,
        UseShellExecute = false,
        CreateNoWindow = true,
        FileName = "runas.exe",
        Arguments = "/user:Administrator cmd /K " + command
    };

    using (Process proc = new Process())
    {
        proc.StartInfo = procStartInfo;
        proc.Start();

        string output = proc.StandardOutput.ReadToEnd();

        if (string.IsNullOrEmpty(output))
            output = proc.StandardError.ReadToEnd();

        return output;
    }
}
