如何在C＃中知道该程序在运行XP SP2的Mac上的Parallels上运行，还是在运行Windows 7的Mac上的VmWare上运行

我正在使用以下代码来指示代码是否在虚拟机上执行。

using (var searcher = new ManagementObjectSearcher("Select * from Win32_ComputerSystem"))
{
    using (var items = searcher.Get())
    {
        foreach (var item in items)
        {
            string manufacturer = item["Manufacturer"].ToString().ToLower();
            Console.WriteLine("Manufacturer: " + manufacturer);
            Console.WriteLine("Model: " + item["Model"].ToString());
            if ((manufacturer == "microsoft corporation" && item["Model"].ToString().ToUpperInvariant().Contains("VIRTUAL"))
                || manufacturer.Contains("vmware")
                || item["Model"].ToString() == "VirtualBox")
            {
                Console.WriteLine("Manufacturer: " + manufacturer);
                Console.WriteLine("Model: " + item["Model"].ToString());
            }
        }
    }
}
Console.Read();

但是除此之外，我还必须知道它是Parallel还是VnWare。任何的想法？谢谢

根据提供的答案，最终代码将是这样，它对我有效ok：

                using (var searcher = new ManagementObjectSearcher("Select * from Win32_ComputerSystem"))
            {
                //TODO: Have to verify the difference between Parallel and Vm
                using (var items = searcher.Get())
                {
                    foreach (var item in items)
                    {
                        string manufacturer = item["Manufacturer"].ToString().ToLower();
                        string model = item["Model"].ToString().ToLower();
                        if (manufacturer.Contains("parallels") && model.Contains("parallels"))
                        {
                            Console.WriteLine("Parallels Detected");
                        }
                        else if(manufacturer.Contains("vmware"))
                        {
                            Console.WriteLine("VMWARE Detected");
                        }
                    }
                }
            }
