暂停/恢复计时器的问题

Question

我有一个迷宫游戏.按Enter键后,您可以输入作弊码,计时器也会暂停.但是在输入代码后,我的计时器恢复,但每秒减少3次.这是按Enter键的条件:

// gt.setTimer() is called at the moment the maze started
// I'm using getch to trap inputs

else if (move == 13) //Reads if Enter is pressed
            {
                pause = 1; //A Flag saying that the timer must be paused
                gt.setTimer(pause); //Calls my setTimer() method
                Console.Write("Enter Cheat: "); 
                cheat = Console.ReadLine();
                pause = 0; //A Flag saying that the timer should resume
                gt.setTimer(lives, pause); //Calls again the Timer
            }

这是我的setTimer()代码:

static System.Timers.Timer t = new System.Timers.Timer();
static int gTime = 300;

public void setTimer(int pause)
    {
        t.Interval = 1000; // Writes the time after every 1 sec
        if (pause == 1)
            t.Stop(); // Stop the timer if you press Enter
        else 
            t.Start(); // Starts the timer if not
        t.Elapsed += new ElapsedEventHandler(showTimer);                       
    }

    public static void showTimer(object source, ElapsedEventArgs e)
    {
        Console.Write("Time   " + gTime); //Writes time
        gTime--; //Decrements the time
    }

有什么不对？我错过了什么吗？

问题出在该setTimer方法的最后一行.计时器处理程序应该在调用构造函数后只注册一次,而不是在setTimer.在elapsed timer事件中,处理程序被称为已注册的次数.因此,您使用的运算符越多+ =被调用的次数越多.
