Generics in C#

Generics:

Generics allow you to delay the specification of the data type of programming elements in a class or a method, until it is actually used in the program. In other words, generics allow you to write a class or method that can work with any data type.

You write the specifications for the class or the method, with substitute parameters for data types. When the compiler encounters a constructor for the class or a function call for the method, it generates code to handle the specific data type. A simple example would help understanding the concept:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

namespace Practice

{

    class Program

    {

        static void Main(string[] args)

        {

    

            G g = new G();

     g.Call();           

        }

    }

}

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

namespace Practice

{

    class G

    {

        class Generics<T>

        {

            public void equality(T x, T y)

            {

                if (x.Equals(y))

                { Console.WriteLine("paramater matched"); }

                else

                { Console.WriteLine("paramater didn't matched"); }

            }

          

        }

        public void Call()

        {

            Generics<int> ig = new Generics<int>();

            ig.equality(12, 8);

            Generics<string> sg = new Generics<string>();

            sg.equality("shoeb", "shoeb");

        }

    }

}

Output:

paramater didn't matched

paramater matched
