How to measure C# console application running time?

Question

I need to bulid an application, that runs under 1 sec, but I cant find out how to determine the running time.

Answer 1

Set up a Stopwatch at initialisation and check its Elapsed property at exit.

Answer 2

        using System;
        using System.Diagnostics;
            //Setting a Stopwatch 
            Stopwatch sw = new Stopwatch();
            sw.Start();
            for (int i = 0; i < length; i++)
            {
                //some logic there
            }
            //Stopping a Stopwatch
            sw.Stop();
            Console.WriteLine(sw.Elapsed);

            //delay
            Console.ReadLine();

This is a simple example of using Stopwatch. But don't forget to write "using System.Diagnostics;", otherwise Stopwatch just won't be founded.

Answer 3

What about using the Stopwatch class.

Particularly notice the note called out on MSDN

On a multiprocessor computer, it does not matter which processor the thread runs on. However, because of bugs in the BIOS or the Hardware Abstraction Layer (HAL), you can get different timing results on different processors. To specify processor affinity for a thread, use the ProcessThread.ProcessorAffinity method.

Answer 4

console application does not close if you write
Console.ReadLine();

Answer 5

You can also get the time at the beginning and at the end of the program, and substract it
