Idle Detection in WPF
问题 I'm new in using WPF so I have no Idea how to detect Idle time and show the main window after 5mins of Idle. Can anyone help me? Thank you so much. 回答1: You can do; var timer = new DispatcherTimer ( TimeSpan.FromMinutes(5), DispatcherPriority.ApplicationIdle,// Or DispatcherPriority.SystemIdle (s, e) => { mainWindow.Activate(); }, // or something similar Application.Current.Dispatcher ); picked up from here 来源： https://stackoverflow.com/questions/23286766/idle-detection-in-wpf
