由 谁说胖子不能爱 提交于 2020-01-11 02:04:11
问题 In my WPF application, the user presses a button to start a 3D model rotating smoothly, and lets up on the button to stop the rotation. To do this, I create a DispatcherTimer: DispatcherTimer timer = new DispatcherTimer(); timer.Tick += new EventHandler( timer_Tick ); timer.Interval = new TimeSpan( 0, 0, 0, 0, 30 ); And when the button is pressed I call timer.Start() and when the button is let up I call timer.Stop() . The timer_Tick function changes the rotation of the model: void timer_Tick(

问题 I'm curious as to why dispatcher timer doesn't work in console mode. I created a simple alarm that does something when the timer reaches it's limit. Can you use dispatcher timer with UnitTest or in Console mode? DailyAlarm works when I run it in a form. Here's my code to call the timer [TestClass] public class UnitTest1 { bool runTest = true; [TestMethod] public void TestDailyAlarm() { DateTime alarmTime = new DateTime(); alarmTime= DateTime.Now; alarmTime = alarmTime.AddSeconds(5); //

问题 I am making a UWP app using the BackgroundAudioTask. My app is working very well. Now I want to add in a TextBlock the Current position of the Audio played. I was doing this method before implementing the audio Task: private TimeSpan TotalTime; private DispatcherTimer timerRadioTime; private void radioPlayer_MediaOpened(object sender, RoutedEventArgs e) { TotalTime = radioPlayer.NaturalDuration.TimeSpan; // Create a timer that will update the counters and the time slider timerRadioTime = new

Most efficient method to update large number of objects (1,000+) in real-time

由 自古美人都是妖i 提交于 2019-12-10 10:17:17
问题 What would be the most efficient way to iterate through a collection with a large number of items (1,000 or more) and update the items' properties in real-time? At the moment, my program draws an image for each object in the collection on a canvas using WriteableBitmap (though I don't see any difference in performance between that an a simple ellipse) and moves it across the screen. I am trying to keep the logic as simple as possible for the time being. <UserControl.Resources> <DataTemplate

Task.Delay vs DispatcherTimer?

由 倾然丶 夕夏残阳落幕 提交于 2019-12-08 15:33:14
问题 I'm considering use Task.Delay() for a non-stop timer, because it's more simple and readable. As I'm new to .NET, I see no significant difference between the two codes. Can you show me the difference (if there is any) between them? // Create variable at some place DispatcherTimer timer = new DispatcherTimer(); timer.Interval = TimeSpan.FromSeconds(5); timer.Tick += timer_Elapsed; timer.Start(); // Function other place void timer_Elapsed(object sender, EventArgs e) { //Do stuff } vs // Every
