タイマーでC＃メソッドを実行するには？

Question

タイマーでC＃メソッドを実行する方法を教えてください。私はオンラインこの例が見つかりましたが、以下のDoStuffOnTimer（）メソッドが打たれていません。

public void DoStuff() 
    { 
     var intervalMs = 5000; 
     var timer = new Timer(intervalMs); 
     timer.Elapsed += new ElapsedEventHandler(DoStuffOnTimer); 
     timer.Enabled = true; 
    } 

    private void DoStuffOnTimer(object source, ElapsedEventArgs e) 
    { 
     //do stuff 
    } 

Answer 1

using System; 
using System.Timers; 

namespace ConsoleApplication1 
{ 
    class Program 
    { 

     static void Main(string[] args) 
     { 
      Program thisone = new Program(); 
      thisone.DoStuff(); 
      Console.Read(); 
     } 

     public void DoStuff() 
     { 
      var intervalMs = 5000; 
      Timer timer = new Timer(intervalMs); 
      timer.Elapsed += new ElapsedEventHandler(DoStuffOnTimer); 
      timer.Enabled = true; 
     } 

     private void DoStuffOnTimer(object source, ElapsedEventArgs e) 
     { 
      //do stuff 
      Console.WriteLine("Tick!"); 
     } 
    } 
} 

Answer 2

をそれとも、非常に正確なタイマーを必要としない場合は、常にそれを自分で作成することができます。

using System; 
using System.Threading; 
using System.Threading.Tasks; 

namespace Temp 
{ 
    internal class Program 
    { 
     // this is the `Timer` 
     private static async Task CallWithInterval(Action action, TimeSpan interval, CancellationToken token) 
     { 
      while (true) 
      { 
       await Task.Delay(interval, token); 
       if (token.IsCancellationRequested) 
       { 
        return; 
       } 

       action(); 
      } 
     } 

     // your method which is called with some interval 
     private static void DoSomething() 
     { 
      Console.WriteLine("ding!"); 
     } 

     // usage sample 
     private static void Main() 
     { 
      // we need it to add the ability to stop timer on demand at any time 
      var cts = new CancellationTokenSource(); 

      // start Timer 
      var task = CallWithInterval(DoSomething, TimeSpan.FromSeconds(1), cts.Token); 

      // continue doing another things - I stubbed it with Sleep 
      Thread.Sleep(5000); 

      // if you need to stop timer, let's try it! 
      cts.Cancel(); 

      // check out, it really stopped! 
      Thread.Sleep(2000); 
     } 
    } 
}
