C# 使用WMI在HyperV VM上应用最新快照时出现错误32775

当我尝试使用WMI将虚拟机还原为最新快照时，我不断收到错误32775（此操作的状态无效）。我正在使用以下代码（顺便提一下，MSDN网站上提供）：

我可以毫无问题地在UI上应用快照，并且我的虚拟机处于启用状态，不做任何事情。操作系统是Windows 2012。我还可以打印快照和虚拟机的名称，这样在识别机器和快照时就不会出现问题

有什么想法吗？ 谢谢

发现了问题，显然，如果要远程应用快照，需要关闭VM！也许在MSDN网站上提到这一点太难了

ManagementObject virtualSystemService = Utility.GetServiceObject(connectionScope,"Msvm_VirtualSystemManagementService");
ManagementBaseObject inParams =virtualSystemService.GetMethodParameters("ApplyVirtualSystemSnapshot");
ManagementObject vmSnapshot = GetLastVirtualSystemSnapshot(vm);
if (vmSnapshot != null)
{
    inParams["SnapshotSettingData"] = vmSnapshot.Path.Path;
    inParams["ComputerSystem"] = vm.Path.Path;
    ManagementBaseObject outParams = virtualSystemService.InvokeMethod("ApplyVirtualSystemSnapshot", inParams, null);
    if ((UInt32)outParams["ReturnValue"] == ReturnCode.Started)
    {
        if (Utility.JobCompleted(outParams, connectionScope))
        {
            Console.WriteLine("Snapshot was applied successfully.");

        }
        else
        {
            Console.WriteLine("Failed to apply snapshot.");
        }
    }
    else if ((UInt32)outParams["ReturnValue"] == ReturnCode.Completed)
    {
        Console.WriteLine("Snapshot was applied successfully.");
    }
    else
    {
        Console.WriteLine("Apply virtual system snapshot failed with error {0}", outParams["ReturnValue"]);
    }
}
else
{
    Console.WriteLine("No Snapshots!");
}
