WPF中的计时器 [英] Timer in wpf

问题描述

public partial class MainWindow : Window
    {
        System.Timers.Timer   t=new   System.Timers.Timer();
                              t.Interval=5000;
         
        public MainWindow()
        {
            this.InitializeComponent();            
            // Insert code required on object creation below this point.
        }
        
   private void Button1_Click(object sender, System.Windows.RoutedEventArgs e)
        {            
            this.media1.Play();
            //mel_Copy.Stop();
            
            t.Enabled=true;
            t.Tick+=new System.EventHandle(this.timer1_Tick);    //here        
            
            //B1
        }

       private void timer1_Tick(object sender, System.EventArgs e)   
                  {
    this.media1.Stop();    
                    }
        }
}

我正在Expression Blend 3中编程，
我想在WPF中使用一个计时器，当用户单击button1时，事件会在5秒后发生(例如)，但是WPF似乎没有
滴答事件！ (t.Tick):confused::(
我添加了System.Timers;
我该怎么办?

I''m programming in Expression blend 3,
I want to use a timer in WPF that when the user clicks the button1, event occurs after 5 sec (for example), but it seems WPF does not have the
Tick event ! ( t.Tick) :confused: :(
I''ve added System.Timers;
What shall I do?

推荐答案

使用DispatcherTimer对象而不是System.Timers.Timer.顺便说一句，使用Google可以轻松回答.

Use the DispatcherTimer object instead of System.Timers.Timer. BTW, this is EASILY answered by using google.

Hi,
Think you are looking for the Elapsed event
See this link[^]

Hope it helps :)

如果无法在XAML中进行设置，则需要按照文档中的说明在C#或VB.NET中进行设置.您发布了代码，因此必须在此处进行.

If you can''t set something in XAML, you need to set it in C# or VB.NET, as the documentation says. You posted code, so that''s where you have to do it.
