How to use interface with properties in C#

Answer 1

using System;

namespace ConsoleApplication_C_Sharp
{

    interface Iinte
    {
        int iq { get; set; } // Property interface
        string user { get; set; } // Property interface
    }

    class Image : Iinte // Implements interface
    {
        public int iq // Property implementation
        {
            get;
            set;
        }

        string _user;

        public string user // Property implementation
        {
            get { return this._user; }
            set { this._user = value; }
        }
    }

    class Article : Iinte
    {
        public int iq 
        {
            get;
            set;
        }

        string _name;

        public string user 
        {
            get { return this._name; }
            set { this._name = value.ToUpper(); }
        }
    }


    class Program
    {
        static void Main(string[] args)
        {
            Iinte inte1 = new Image();
            Iinte inte2 = new Article();

            inte1.iq++; 
            inte2.iq += 13;

            inte1.user = "3-PO";
            inte2.user = "R2-D2"; 

            Console.WriteLine(inte1.user + " : " + inte1.iq); 
            Console.WriteLine(inte2.user + " : " + inte2.iq);
        }
    }
}


/*
run:
     
3-PO : 1
R2-D2 : 13
 
*/
