  您正在寻找的示例在visual studio中提供的默认模板中不存在 . 有一个项目可以创建具有此功能的模板 . 你可以在...找到这些模板

  https://github.com/Windows-XAML/Template10

  以下是模板10中有关挂起和恢复的代码

  Resuming += (s, e) => { OnResuming(s, e); };
              Suspending += async (s, e) =>
              {
                  // one, global deferral
                  var deferral = e.SuspendingOperation.GetDeferral();
                  try
                  {
                      foreach (var service in WindowWrapper.ActiveWrappers.SelectMany(x => x.NavigationServices))
                      {
                          // date the cache (which marks the date/time it was suspended)
                          service.FrameFacade.SetFrameState(CacheDateKey, DateTime.Now.ToString());
                          // call view model suspend (OnNavigatedfrom)
                          await service.SuspendingAsync();
                      }
                      // call system-level suspend
                      await OnSuspendingAsync(s, e);
                  }
                  catch { }
                  finally { deferral.Complete(); }
              };
