ApplySnapshot示例Hyper-V V2

Question

我正在嘗試使用C＃和ApplySnapshot方法將快照應用於Hyper V虛擬機。

ApplySnapshot方法

但是我似乎很掙扎，因為該方法沒有示例類。 如果有人可以幫助提供示例或示例項目，我將不勝感激。

非常感謝

本示例將為VM應用最新快照。 通過使用代表您要應用的快照的Msvm_VirtualSystemSettingData實例替換“ lastSnapshot”，可以輕松地將其更改為應用選定的快照。

public static class VirtualSystemSnapshot
{
    public static object Revert(VirtualMachine vm)
    {
        ManagementScope scope = new ManagementScope("\\\\" + ServerName + "\\Root\\Virtualization\\V2", Options);
        using (ManagementObject virtualMachine = WmiUtilities.GetVirtualMachine(vmElementName, scope)) {
            using (ManagementObject virtualSystemSettingData = WmiUtilities.GetVirtualSystemSettingData(scope, virtualMachine)) {
                using (ManagementObject virtualSystemSnapshotService = WmiUtilities.GetVirtualSystemSnapshotService(scope)) {
                    using (ManagementObject lastSnapshot = WmiUtilities.GetFirstObjectFromCollection(virtualSystemSettingData.GetRelated("Msvm_VirtualSystemSettingData", "Msvm_ParentChildSettingData", null, null, null, null, false, null))) {
                        using (ManagementBaseObject inParams = virtualSystemSnapshotService.GetMethodParameters("ApplySnapshot")) {
                            inParams("Snapshot") = lastSnapshot;

                            // In order to apply a snapshot, the virtual machine must first be saved
                            RequestStateChange.Main(vm, RequestStateChange.RequestedState.Save, false);

                            using (ManagementBaseObject outParams = virtualSystemSnapshotService.InvokeMethod("ApplySnapshot", inParams, null)) {
                                WmiUtilities.ValidateOutput(outParams, scope);

                                // Now that the snapshot has been applied, start the VM back up
                                RequestStateChange.Main(vm, RequestStateChange.RequestedState.Start, false);
                            }
                        }
                    }
                }
            }
        }
    }
}
