将Int转换为String以显示时间

帮我写代码。我试图使用ToString()方法将int转换为time格式。当我运行它时，我得到09:100。我可以做什么，特别是使用getters和setters ?

public struct Time
{
    public int hours;
    public int minutes;
    public Time(int hh, int mm)
    {
        this.hours = hh;
        this.minutes = mm;
    }
    public int hh { get { return hours; } set { hours = value % 60; } }
    public int mm { get { return minutes; } set { minutes = value % 60; } }
    public override string ToString()
    {
        return String.Format("{0:00}:{1:00}", hh, mm);
    }
    public static implicit operator Time(int t)
    {
        int hours = (int)t / 60;
        int minutes = t % 60;
        return new Time(hours, minutes);
    }
    public static explicit operator int(Time t)
    {
        return t.hours * 60 + t.minutes;
    }
    public static Time operator +(Time t1, int num)
    {
        int total = t1.hh * 60 + t1.mm + num;
        int h = (int)(total / 60) % 24,
            m = total % 60;
        return new Time(h, m);
    }
    public int Minutes { get { return minutes; } set { minutes = value % 60; } }
    class Program
    {
        static void Main(string[] args)
        {
            Time t1 = new Time(9, 30);
            Time t2 = t1;
            t1.minutes = 100;
            Console.WriteLine("The time is: 'nt1={0}  'nt2={1} ", t1, t2);
            Time t3 = t1 + 45;
        }
    }
}

将Int转换为String以显示时间

在main method change t1.minutes = 100; to t1.Minutes = 100;中，
代码如下:

public struct Time
{
private int hours;
private int minutes;
public Time(int hh, int mm)
{
    this.hours = hh;
    this.minutes = mm;
}
public int hh { get { return hours; } set { hours = value % 60; } }
public int mm { get { return minutes; } set { minutes = value % 60; } }
public override string ToString()
{
    return String.Format("{0:00}:{1:00}", hh, mm);
}
public static implicit operator Time(int t)
{
    int hours = (int)t / 60;
    int minutes = t % 60;
    return new Time(hours, minutes);
}
public static explicit operator int(Time t)
{
    return t.hours * 60 + t.minutes;
}
public static Time operator +(Time t1, int num)
{
    int total = t1.hh * 60 + t1.mm + num;
    int h = (int)(total / 60) % 24,
        m = total % 60;
    return new Time(h, m);
}
public int Minutes { get { return minutes; } set { minutes = value % 60; } }
class Program
{
    static void Main(string[] args)
    {
        Time t1 = new Time(9, 30);
        Time t2 = t1;
        t1.minutes = 100;
        Console.WriteLine("The time is: 'nt1={0}  'nt2={1} ", t1, t2);
        Time t3 = t1 + 45;
    }
}
}

好的做法:hours和minutes变量应该是private而不是public，如果你提供getter和setter。

我不知道你的确切要求，但我认为下面的代码

public int Minutes { get { return minutes; } set { minutes = value % 60; } }

应该替换为以下内容:

public int Minutes { 
        get { return minutes; } 
        set {
            if (value > 60)
                hours = hours + (int)value / 60;
            minutes = value % 60; 
        } 
    }
