public static void DetachVirtualHardDisk(string path)
{
    ManagementScope scope = new ManagementScope(@"root\virtualization\V2", null);

    ManagementClass mountedStorageImageServiceClass = new ManagementClass("Msvm_MountedStorageImage");

    mountedStorageImageServiceClass.Scope = scope;

    using (ManagementObjectCollection collection = mountedStorageImageServiceClass.GetInstances())
    {
        foreach (ManagementObject image in collection)
        {
            using (image)
            {
                string name = image.GetPropertyValue("Name").ToString();
                if (string.Equals(name, path, StringComparison.OrdinalIgnoreCase))
                {
                    ManagementBaseObject outParams = image.InvokeMethod("DetachVirtualHardDisk", null, null);

                    if ((UInt32)outParams["ReturnValue"] == 0)
                    {
                        Console.WriteLine("{0} was detached successfully.", path);
                    }
                    else
                    {
                        Console.WriteLine("Unable to dettach {0}", path);
                    }

                    outParams.Dispose();

                    break;
                }

                image.Dispose();
