Demo

using System;
using System.Diagnostics;

class Program/*from w ww. ja  v a  2  s  . c om*/
{
    static void Main(string[] args)
    {
        #region without casting operations
        Stopwatch myStopwatch1 = new Stopwatch();
        myStopwatch1.Start();
        for (int i = 0; i < 100000; i++)

            int j = 25;
            int myInt = j;
        }
        myStopwatch1.Stop();
        Console.WriteLine("Time taken without casting : {0}", myStopwatch1.Elapsed);
        #endregion
        #region with casting operations
        Stopwatch myStopwatch2 = new Stopwatch();
        myStopwatch2.Start();
        for (int i = 0; i < 100000; i++)
        {
            double myDouble = 25.5;
            int myInt = (int)myDouble;
        }
        myStopwatch2.Stop();
        Console.WriteLine("Time taken with casting: {0}", myStopwatch2.Elapsed);
