[C#] 코드 실행 시간 측정

테스트 목적으로 절차 / 기능 / 주문이 완료되는 데 걸리는 시간을 알고 싶습니다.

이것은 내가 한 일이지만 초 차이가 0이면 경과 된 밀리 초를 반환 할 수 없기 때문에 내 방법이 잘못되었습니다.

절전 값이 500ms이므로 경과 된 초가 0이면 밀리 초를 반환 할 수 없습니다.

    Dim Execution_Start As System.DateTime = System.DateTime.Now
    Threading.Thread.Sleep(500)

    Dim Execution_End As System.DateTime = System.DateTime.Now
    MsgBox(String.Format("H:{0} M:{1} S:{2} MS:{3}", _
    DateDiff(DateInterval.Hour, Execution_Start, Execution_End), _
    DateDiff(DateInterval.Minute, Execution_Start, Execution_End), _
    DateDiff(DateInterval.Second, Execution_Start, Execution_End), _
    DateDiff(DateInterval.Second, Execution_Start, Execution_End) * 60))

누군가가 더 나은 방법을 보여줄 수 있습니까? 어쩌면 TimeSpan?

해결책:

Dim Execution_Start As New Stopwatch
Execution_Start.Start()

Threading.Thread.Sleep(500)

MessageBox.Show("H:" & Execution_Start.Elapsed.Hours & vbNewLine & _
       "M:" & Execution_Start.Elapsed.Minutes & vbNewLine & _
       "S:" & Execution_Start.Elapsed.Seconds & vbNewLine & _
       "MS:" & Execution_Start.Elapsed.Milliseconds & vbNewLine, _
       "Code execution time", MessageBoxButtons.OK, MessageBoxIcon.Information)

Stopwatch stopwatch = Stopwatch.StartNew(); //creates and start the instance of Stopwatch
//your sample code
System.Threading.Thread.Sleep(500);
stopwatch.Stop();
Console.WriteLine(stopwatch.ElapsedMilliseconds);

// Create new stopwatch
Stopwatch stopwatch = new Stopwatch();

// Begin timing
stopwatch.Start();

Threading.Thread.Sleep(500)

// Stop timing
stopwatch.Stop();

Console.WriteLine("Time elapsed: {0}", stopwatch.Elapsed);

public class Benchmark : IDisposable
{
    private readonly Stopwatch timer = new Stopwatch();
    private readonly string benchmarkName;

    public Benchmark(string benchmarkName)
    {
        this.benchmarkName = benchmarkName;
        timer.Start();
    }

    public void Dispose()
    {
        timer.Stop();
        Console.WriteLine($"{benchmarkName} {timer.Elapsed}");
    }
}

using (var bench = new Benchmark($"Insert {n} records:"))
{
    ... your code here
}

Insert 10 records: 00:00:00.0617594

var watch = System.Diagnostics.Stopwatch.StartNew();
/* the code that you want to measure comes here */
watch.Stop();
var elapsedMs = watch.ElapsedMilliseconds;

TimeSpan startTime= Process.GetCurrentProcess().Threads[i].UserProcessorTime; // i being your thread number, make it 0 for main
//Write your function here
TimeSpan duration = Process.GetCurrentProcess().Threads[i].UserProcessorTime.Subtract(startTime);

Console.WriteLine($"Time caluclated by CurrentProcess method: {duration.TotalSeconds}"); // This syntax works only with C# 6.0 and above

        Dim Stopwatch As New Stopwatch

        Stopwatch.Start()
                    ''// Test Code
        Stopwatch.Stop()
        Console.WriteLine(Stopwatch.Elapsed.ToString)

        Stopwatch.Restart()
                   ''// Test Again

        Stopwatch.Stop()
        Console.WriteLine(Stopwatch.Elapsed.ToString)
