stop watch

Stop watch and timer and alarm, using the Stopwatch class in C#, useful in cases to measure how long your program takes to run:
csharp code

using System;
using System.Diagnostics;
using System.Threading;

class Program
{
    static void Main()
    {
	// Creating an instance of Stopwatch
	Stopwatch myWatch = new Stopwatch();

	// Start counting 
	myWatch.Start();

	// Any thing that take time
	for (int i = 0; i < 200; i++)
	{
          // Sleep 
	    Thread.Sleep(1);
	}

	// Stop the watch
	myWatch.Stop();

	// Write result
	Console.WriteLine("Your program took :time elapsed: {0}",
	    myWatch.Elapsed);
    }
}

You can also restart the stop watch using "restart function" :
csharp code

using System;
using System.Diagnostics;
using System.Threading;

class Program
{
    static void Main()
    {
	Stopwatch myWatch = Stopwatch.StartNew();
        // Sleep for five seconds
	Thread.Sleep(5000);
        // Restart the time counter
	stop.Restart();
        // Sleep again
	Thread.Sleep(2000);
        // The time difference should be 2 seconds only.
	Console.WriteLine(stop.ElapsedMilliseconds);
    }
}
