In the following code, I am trying to declare a read-only property Hour returning the number of hours and
a read-only property Minute returning the number of minutes. For instance, new Time(23, 45).Minute
should be 45.
I need to modify the ToString() method so that it shows a Time in the format hh:mm, for instance 10:05, instead
of 605. How can I use String.Format to do the formatting in the Main() Method?
 
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
using System.Timers;
namespace TestTime
{
    class Program
    {
        static void Main(string[] args)
        {
           
            Time timenow =  new Time(1,2);
            Console.WriteLine("Time={0} ", timenow);
            Console.WriteLine("Press Any Key");
            Console.ReadKey();
        
        }
        public struct Time
        {
            public readonly int minutes;
            public Time(int hh, int mm)
            {
                Console.WriteLine("Enter Hour");
                hh = Int32.Parse( Console.ReadLine());
                Console.WriteLine("Enter Min");
                mm = Int32.Parse( Console.ReadLine());
                this.minutes = 60 * hh + mm;
            }
            public override String ToString()
            {
                return minutes.ToString();
            }

        } 
    }
}
