C# 类实例特定计时器经过事件

Question

在我的程序中，我需要生成一个名为“Vehicle”的类的实例，当计时器达到一个间隔时，Vehicle 类中有一个计时器，以及一个布尔值“vExists”。

class VehicalGen
{
    private Random rn1 = new Random();

    private int agrotime;
    private bool vExists;
    //static AgrivationHandler agroTimeHandler;
    private static Timer agroTimer = new Timer(100);

    //agrotime: anywhere between 2 and 4 seconds (2000 to 4000)

    ///Generates the new Vehicles using GetCarType to change the outcome of the later variables
    public VehicalGen()
    {
        this.vtype = RandomGeneration.GetCarType(rn1);
        switch (this.vtype)
        {
            [....] //This is where the details of the vehicle are generated.
        }
        this.agrotime = RandomGeneration.GetRandomTime224(rn1);
        this.vExists = true;
        this.serviced = false;
        //agroTimeHandler = new AgrivationHandler(agrotime);
        agroTimer.Interval = agrotime;
        agroTimer.Elapsed += AgroTimerElapsed;
        agroTimer.Start();
    }

    public static void AgroTimerElapsed(object sender, ElapsedEventArgs e)
    {
        //here is where I need to set vExists to "False"
    }
}

但是，据我所知，我需要生成该类的特定实例，因为它不喜欢“this.vExists = false”，它只是错误。

是的，是可能的。 请尝试以下操作：

private void LoadTimer()
   Timer timer = new Timer
   timer.Interval = 4000;
   timer.Enabled = true; 
   timer.Tick += new EventHandler(timer1_Tick);
   timer.Start(); 
}

private void timer1_Tick(object sender, EventArgs e)
{
   // do your boolean operation where
}
