Generic in C# with example?

Generic can be defined as <T> sign after the class name, by using the generic there is no need of boxing and unboxing. Generic also can be implemented with interfaces, delegates and methods.

Example:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Windows.Forms;

namespace WindowsFormsApplication1

{

    class Class1<T>

    {

        T i;

        public T prop1

        {

            get

            {

                return i;

            }

            set

            {

                i = value;

            }

        }

    }

}

Code on button click:

Class1<int> obj = new Class1<int>();

        private void button1_Click(object sender, EventArgs e)

        {

            obj.prop1 = 100;

            int x = obj.prop1;

            MessageBox.Show(x.ToString());

        }

Output : 100
