ApplySnapshot示例Hyper-V V2

Question

我想将快照应用于使用C＃的超V虚拟机并使用ApplySnapshot方法。

ApplySnapshot method

但我似乎因为没有挣扎样品类为该方法。如果有人能够帮助提供样本或样本项目，我会很乐意。

非常感谢

这个例子将应用最新的快照虚拟机。通过将'lastSnapshot'替换为表示您想要应用的快照的Msvm_VirtualSystemSettingData实例，可以轻松更改此选项以应用选定的快照。

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); 
          } 
         } 
        } 
       } 
      } 
     } 
    } 
}
