使用 .NET 检查远程桌面服务 (RDS)/远程桌面会话主机 (RDSH) 是否安装在 Windows 服务器上

Question

我需要使用 .NET 检测远程桌面会话主机是否安装在 Windows 2008 - 2019 中，作为我们产品的先决条件检查器的一部分。在 RDS 服务器上无法以执行模式安装某些部件，所以我必须告诉用户，他必须更改为安装模式...

从 Windows Server 2008 起，您可以使用以下类型的代码检查是否安装了 RDS 角色：

static void Main(string[] args)
{
    // 14 is the identifier of the Remote Desktop Services role.
    HasServerFeatureById(14);
}

static bool HasServerFeatureById(UInt32 roleId)
{
    try
    {
        ManagementClass serviceClass = new ManagementClass("Win32_ServerFeature");
        foreach (ManagementObject feature in serviceClass.GetInstances())
        {
            if ((UInt32)feature["ID"] == roleId)
            {
                return true;
            }
        }

        return false;
    }
    catch (ManagementException)
    {
        // The most likely cause of this is that this is being called from an 
        // operating system that is not a server operating system.
    }

    return false;
}
