List：自定义对象如何从列表中删除自身？

发布于 2024-11-17 00:07:08 字数 552 浏览 1 评论 0原文

我创建了一个类，它实现了带有 elapse 事件的 System.Timers.Timer 。


private void ElapseEvent(object source, ElapsedEventArgs e){
//read from serial port device
}

在主程序中，我有一个 private List; _计时器。

我动态启动计时器并将其添加到计时器列表中。


 var timer1= new MyTimerClass();
 timer1.Execute("Device A");
_timers.Add(timer1);

 var timer2= new MyTimerClass();
 timer2.Execute("Device B");
_timers.Add(timer2);

当ElapseEvent遇到错误并且串口断开连接时，我想从列表中删除计时器。我怎么可能这么做呢？

原文

I created a class that implements a System.Timers.Timer with an elapse event.


private void ElapseEvent(object source, ElapsedEventArgs e){
//read from serial port device
}

In the main program I have a private List<MyTimerClass> _timers.

I dynamically start the timer and add it to the timer list.


 var timer1= new MyTimerClass();
 timer1.Execute("Device A");
_timers.Add(timer1);

 var timer2= new MyTimerClass();
 timer2.Execute("Device B");
_timers.Add(timer2);

When the ElapseEvent encounters an error and the serial port was disconnected, I want to remove the timer from the List. How can I possibly do that?

您可以在包含计时器的类中添加 OnError 方法。为了让父类知道发生了错误。类似于以下内容：

在 MyTimerClass

public MyTimerClass(Action<MyTimerClass, Exception> onError)
{
    this.onError = onError;
}

private void ElapseEvent(object source, ElapsedEventArgs e){
try{
//read from serial port device
}
catch(Exception ex) // It would be better if you know the exceptions you want to handle
{
  if(this.onError != null)
  {
   this.onError(this, ex);
  }
}
}

在父类中：

var timer1= new MyTimerClass(this.OnTimerError);
 timer1.Execute("Device A");
_timers.Add(timer1);

 var timer2= new MyTimerClass(this.OnTimerError);
 timer2.Execute("Device B");
_timers.Add(timer2);



public void OnTimerError(MyTimerClass timer, Exception error)
{
 //Log the exception
  _timers.Remove(timer);
}

You can add a OnError Method at the class that contains the timers. In order to let the parent class know that an error occurs. Something like the following:

At MyTimerClass

public MyTimerClass(Action<MyTimerClass, Exception> onError)
{
    this.onError = onError;
}

private void ElapseEvent(object source, ElapsedEventArgs e){
try{
//read from serial port device
}
catch(Exception ex) // It would be better if you know the exceptions you want to handle
{
  if(this.onError != null)
  {
   this.onError(this, ex);
  }
}
}

At the parent class:

var timer1= new MyTimerClass(this.OnTimerError);
 timer1.Execute("Device A");
_timers.Add(timer1);

 var timer2= new MyTimerClass(this.OnTimerError);
 timer2.Execute("Device B");
_timers.Add(timer2);



public void OnTimerError(MyTimerClass timer, Exception error)
{
 //Log the exception
  _timers.Remove(timer);
}
