How can i measure time of some part of code considering sleep time?

I try this:

Stopwatch timer = new Stopwatch();
timer.Start();

for (i = 0; i < 100; i++) {
    //do here some stuff
    Thread.Sleep(500);
}

timer.Stop();
TimeSpan ts = timer.Elapsed;
Console.WriteLine(ts.Milliseconds);

And it show me 49 milliseconds, but in fact it was performed in like 2 minutes. It's educational tusk and i have to consider sleep time. How can i do this?

The Timespan.Milliseconds property returns the millisecond part of the timespan, after subtracting elapsed seconds, minutes, hours, etc. You probably want TimeSpan.TotalMilliseconds.

See this post for the explanation: C# Timespan Milliseconds vs TotalMilliseconds

Use of Stopwatch will not be accurate, if you want a precise measurement of the execution of some code you will have to use the performance counters that's built into the operating system. Check this out.

I think it is a unit problem, try getting ms directly from stopwatch, this worked for me: 

    Stopwatch timer = new Stopwatch();
    timer.Start();

    for (int i = 0; i < 20; i++)
    {
        //do here some stuff
        Thread.Sleep(500);
    }

    timer.Stop();
    long ms =  timer.ElapsedMilliseconds;
    Console.WriteLine(ms);
    Console.ReadLine();
