Understanding Implicit and Explicit in Conversion Operators (C# reference)

In the below example it has duplicates for each of the type casting. So for understanding I included both but commented the code. If you want to give it a try please uncomment the operator with corresponding colored typecast method to statements in Main

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

namespace Apps

{

    class MyTime1

    {

        public int h { set; get; }

        public int m { set; get; }

        public int s { set; get; }

        public MyTime1(int h, int m, int s)

        {

            this.h = h;

            this.m = m;

            this.s = s;

        }

        public MyTime1(int h)

        {

            this.h = h;

        }

        public int TotalSeconds

        {

            get

            {

                return h * 3600 + m * 60 + s;

            }

        }

        //public static implicit operator int(MyTime1 t1)

        //{

        //    return t1.TotalSeconds;

        //}

        //public static explicit operator int(MyTime1 t2)

        //{

        //    return t2.TotalSeconds;

        //}

        //public static implicit operator MyTime1(int n)

        //{

        //    return new MyTime1(n);

        //}

        public static explicit operator MyTime1(int n)

        {

            return new MyTime1(n);

        }

    class UnderstandingImplicitAndExplicitOverloading

    {

        public static void Main()

        {

            MyTime1 t1 = new MyTime1(10, 59, 59); 

            //int sec1 = t1;       // convert from int to class object IMPLICITLY

            //Console.WriteLine(sec1);

            //int sec2 = (int)t1;   // convert from int to class object EXPLICITLY

            //Console.WriteLine(sec2);

            // Constructor Overloading takes place. other form MyTime t2 = new MyTime(60);

            //MyTime1 t2 = 10;         // convert from class object to int IMPLICITLY

            MyTime1 t2 = (MyTime1)10;         // convert from class object to int EXPLICITLY

            Console.WriteLine(t2.TotalSeconds);

            Console.WriteLine(t1.TotalSeconds);

        }
