Hi,

Constructor is used to initialize an object (instance) of a class and it has the same name as the class name. Constructor is a like a method without any return type.

Example : Count Instances Of The Class Using Constructor
using System;

namespace data
{
    public class test
    {
        public static int count = 0;
        public test()
        {
            count = count + 1;
        }
    }

    public class Program
    {
        public static void Main()
        {
            test obj1 = new test();
            test obj2 = new test();
            test obj3 = new test();
            test obj4 = new test();
            Console.WriteLine(data.test.count);
        }
    }
}

When a class or struct is created, its constructor is called. Constructors have the same name as the class or struct, and they usually initialize the data members of the new object.
