我想通过 powershell 安装一些功能。即使它没有安装任何功能也会PSObject返回。Installed

环境：Windows Server 2019 x64，应用：.NET Framework + PowerShellStandard.Library 5.1

应用程序是为 x64 构建的以运行ServerManager模块。

安装功能的代码，例如管理控制台

InstallWindowsFeature(powerShell, "Web-Mgmt-Console");

安装功能

void InstallWindowsFeature(PowerShell powerShell, string featureName)
{
    if(IsWindowsFeatureInstalled(powerShell, featureName)) // Get-WindowsFeature call..
    {
        Console.WriteLine($"{featureName} is already installed. Skipping install...");

        return;
    }
    
    powerShell.AddCommand("Install-WindowsFeature");
    powerShell.AddParameter("Name", featureName);

    Collection<PSObject> psObjects = powerShell.Invoke();

    foreach (dynamic psObject in psObjects.Where(x => x != null))
        Console.WriteLine($"Result: Success - {psObject.Success}, Restart needed: {psObject.RestartNeeded}, Exit code: {psObject.ExitCode}");
}

PowerShell 初始化

    InitialSessionState initialSessionState = InitialSessionState.CreateDefault();
    initialSessionState.ImportPSModule(new string[] { "ServerManager" });

    Runspace powerShellRunscape = RunspaceFactory.CreateRunspace(initialSessionState);

    powerShellRunscape.Open();

    PowerShell powerShell = PowerShell.Create();

    powerShell.Runspace = powerShellRunscape;

    // install call

    powerShell.Dispose();

    powerShellRunscape.Close();

如何正确运行 Install-WindowsFeature？
