Write a program to find the program execution time in c#

namespace TodayTask
{
    class Program
    {        
         static void Main(string[] args)
        {
            var stopWatch = new Stopwatch();

            //start measuring the initial time of the program
            stopWatch.Start(); 

            //do some heavy work
            Enumerable
                .Range(1, 200000)
                .ToList()
                .ForEach(i => Console.WriteLine(i));

            //finally stop the watch    
            stopWatch.Stop();

            //measure the total executuion time
            Console.WriteLine(stopWatch.ElapsedTicks);
            Console.ReadLine();
        }
    }
