C#中操作符的重载(Time类)

今天在写一个计时器的Time类,其中想写一些比较简单的方法,所以用到了C#中的操作符的重载,以前会写的居然只有C++的操作符重载,原来自己没遇到过,居然却不会写C# 的操作符重载(虽然C# 的操作符重载要简单得多,但是真正写出来了,才是硬道理啊!)

下面附上我写的Time类,里面有个操作符“++”的重载,“++”的重载会在后面的应用中简单很多呢。。

    class Time
    {
        private int hours;
        private int minutes;
        private int seconds;

        public Time()
        {
            this.hours = 0;
            this.minutes = 0;
            this.seconds = 0;
        }

        public Time(int hours, int minutes, int seconds)
        {
            this.hours = hours;
            this.minutes = minutes;
            this.seconds = seconds;
        }

        public void SetHours(int hours)
        {
            this.hours = hours;
        }
        public void SetMinutes(int minutes)
        {
            this.minutes = minutes;
        }
        public void SetSeconds(int seconds)
        {
            this.seconds = seconds;
        }

        public int GetHours()
        {
            return this.hours;
        }
        public int GetMinutes()
        {
            return this.minutes;
        }
        public int GetSeconds()
        {
            return this.seconds;
        }

        public static Time operator ++(Time time)  //++操作符的重载。。以前居然没写过。。
    {
        time.seconds++;
        if (time.seconds >= 60)
        {
            time.minutes++;
            time.seconds = 0;
            if (time.minutes >= 60)
            {
                time.hours++;
                time.minutes = 0;
                if (time.hours >= 24)
                {
                    time.hours = 0;
                    time.seconds = 0;
                    time.minutes = 0;
                }
            }
        }
        return new Time(time.hours, time.minutes, time.seconds);
    }

    }

Time类还有很多的功能没写,先上着用,有机会完善,而且这个类也太简单了。。尴尬
