C# – Example of Class with Two Constructors – Video

Posted on January 22, 2014 by

Sometimes you should create more than one constructor for a class. This is a useful practice, if you need to generate objects of the same type which need to be initiated with different fields. In the current example, we generate four objects – “Football Teams” and we define these football teams with a “Name”, “FamousPlayer”, “City” and “Country”. Furthermore, we develop a simple void method, which gives us information for those football teams.
The teams are put in an array and with a foreach loop the method given information is called. At the end of the program we have the following:

which is pretty much what we wanted to achieve.

One last interesting note – for the execution of the method the objects are put into an array. Then with the help of a foreach loop, the method is called for each one of them.

Here comes the code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace FootballNames
{
    class ClubInfo
    {
        private string name;
        private string famousPlayer;
        private string city;
        private string country;

        public ClubInfo()
        {
            this.name = "Some name";
            this.famousPlayer = "Some Player";
            this.city = "some city";
            this.country = "some country";
        }

        public ClubInfo(string name, string famousPlayer, string city, string country)
        {
            this.name = name;
            this.famousPlayer = famousPlayer;
            this.city = city;
            this.country = country;
        }

        public void GiveInfo()
        {
            Console.WriteLine("{0} is from {1}, {2}. {3} plays there.",name,city, country,famousPlayer);
        }
    }
}
