Question

我正在创建一个程序，其中timer1应该激活另一个timer2然后停止，在timer2中我再次激活timer1并停止timer2然后继续然后我有一个文本日志，它写下进度。这是问题所在，首先它以2的Timer1滴答开始然后2的定时器2然后它再乘以2所以它的4下一次然后是8然后16这样，我只想要它是1个timer1而不是1个timer2然后它重新开始，我看不出有什么问题。

private void buttonStart_Click(object sender, EventArgs e)
{
    buttonStart.Enabled = false;
    buttonStop.Enabled = true;

    timer1.Tick += new EventHandler(timer1_Tick); 
    timer1.Interval = (1000);             
    timer1.Enabled = true;                       
    timer1.Start();

}

private void buttonStop_Click(object sender, EventArgs e)
{
    buttonStart.Enabled = true;
    buttonStop.Enabled = false;

    timer1.Stop();
    timer2.Stop();
}

private void LogWrite(string txt)
{
    textBoxCombatLog.AppendText(txt + Environment.NewLine);
    textBoxCombatLog.SelectionStart = textBoxCombatLog.Text.Length;
}

private void timer1_Tick(object sender, EventArgs e)
{
    LogWrite(TimeDate + "player hit");

    timer1.Stop();

    timer2.Tick += new EventHandler(timer2_Tick);
    timer2.Interval = (1000);
    timer2.Enabled = true;
    timer2.Start();


}

private void timer2_Tick(object sender, EventArgs e)
{
    LogWrite(TimeDate + "mob hit");

    timer2.Stop();

    timer1.Tick += new EventHandler(timer1_Tick);
    timer1.Interval = (1000);
    timer1.Enabled = true;
    timer1.Start();

}

Answer 1

在timer1_tick上您将事件添加到timer2.tick事件，因此每次timer1_tick函数引发时，您都会向timer2添加一个事件侦听器，但永远不会删除旧事件处理程序，与timer2_tick相同的情况。

我的建议是将这些行添加到构造函数中，并从其他函数中删除这些行：

timer1.Tick += new EventHandler(timer1_Tick); 
timer1.Interval = (1000);             
timer1.Enabled = true;   

timer2.Tick += new EventHandler(timer2_Tick);
timer2.Interval = (1000);
timer2.Enabled = true;

如果你这样做，你的计时器每次打勾只会调用一次。

我确定这就是@ Epsil0neR的意思......

public partial class Form1 : Form
{

    public Form1()
    {
        InitializeComponent();

        timer1.Tick += new EventHandler(timer1_Tick);
        timer1.Interval = (1000);
        timer1.Enabled = false;

        timer2.Tick += new EventHandler(timer2_Tick);
        timer2.Interval = (1000);
        timer2.Enabled = false;
    }

    private void buttonStart_Click(object sender, EventArgs e)
    {
        buttonStart.Enabled = false;
        buttonStop.Enabled = true;

        timer1.Start();
    }

    private void buttonStop_Click(object sender, EventArgs e)
    {
        timer1.Stop();
        timer2.Stop();

        buttonStart.Enabled = true;
        buttonStop.Enabled = false;
    }

    private void LogWrite(string txt)
    {
        textBoxCombatLog.AppendText(txt + Environment.NewLine);
        textBoxCombatLog.SelectionStart = textBoxCombatLog.Text.Length;
    }

    private void timer1_Tick(object sender, EventArgs e)
    {
        timer1.Stop();

        LogWrite(TimeDate + "player hit");

        timer2.Start();
    }

    private void timer2_Tick(object sender, EventArgs e)
    {
        timer2.Stop();

        LogWrite(TimeDate + "mob hit");

        timer1.Start();
    }

    private string TimeDate
    {
        get { return DateTime.Now.ToString("HH:mm:ss") + ": "; }
    }

}

计时器一次打勾超过1次
