Running time of a program in C#

Question

I have written some C# Console application which I want to test for their running times. Does the language or Visual Studio provide any such facility? What is the best way to do this?

Answer 1

You can use the Stopwatch class.

using System;

using System.Collections.Generic;

using System.Text;

using System.Diagnostics;

namespace Timing

{

public class AlgorithmTimer

{

private TimeSpan startingTime, duration;

public AlgorithmTimer()

{

startingTime = new TimeSpan(0);

duration = new TimeSpan(0);

}

public void StartTime()

{

GC.Collect();

GC.WaitForPendingFinalizers();

startingTime = Process.GetCurrentProcess().UserProcessorTime;

}

public void StopTime()

{

duration = Process.GetCurrentProcess().UserProcessorTime.Subtract(startingTime);

}

public TimeSpan Result

{

get { return duration; }

}

}

}

Answer 3

I compiled that into a dll and here is a test run:

using System;

using System.Collections.Generic;

using System.Text;

using Timing;

namespace TestingTimingClass

{

class Program

{

static void Main(string[] args)

{

int[] numbers = new int[9999];

BuildArray(numbers);

AlgorithmTimer at = new AlgorithmTimer();

at.StartTime();

DisplayNums(numbers);

at.StopTime();

Console.WriteLine("Time was " + at.Result.TotalSeconds + " seconds");

Console.ReadLine();

}

private static void BuildArray(int[] arr)

{

for (int i = 0; i < 9999; i++)

{

arr[i] = i;

}

}

private static void DisplayNums(int[] arr)

{

for (int i = 0; i <= arr.GetUpperBound(0); i++)

{

Console.WriteLine(arr[i]);

}

}

}

}
