C# program for swapping using generics

We are using this program to swap any type of data using Generics.

using System;
using System.Collections.Generic;

namespace SwapingUsingGenerics
{



    class Program
    {
        static void swap<T>(ref T a,ref T b)
        {
            T temp = a;
            a = b;
            b = temp;
        }
        static void Main(string[] args)
        {
            string s1 = "tushar";
            string s2 = "patel";
            int i = 10;
            int j = 22;

            Console.WriteLine("Before swapping:s1={0},s2={1}",s1,s2);
            swap<string>(ref s1,ref s2);
            Console.WriteLine("Before swapping:s1={0},s2={1}",s1,s2);

            Console.WriteLine("Before swapping:i={0},j={1}",i,j);
            swap<int>(ref i, ref j);
            Console.WriteLine("after swapping:i={0},j={1}",i,j);

        }
    }
}

Note:- In this program we are swaping any type of data. Notice that we are using only one Generic type method.
