检测是否已安装远程桌面服务角色

可以使用 Win32_ServerFeature WMI 类来检测是否已安装远程桌面服务服务器角色。

下面的 C# 示例演示了一个方法,该方法在已安装并运行远程桌面服务服务器角色时返回 True ,否则返回 false 。 由于 Win32_ServerFeature WMI 类仅从 Windows Server 2008 开始可用,因此此代码与早期版本的 Windows 不兼容。

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;
}
