Stopwatch.Stop Method (System.Diagnostics)

.NET Framework Class Library

Stopwatch..::.Stop Method

Updated: August 2008

Stops measuring elapsed time for an interval.

Namespace: System.Diagnostics
Assembly: System (in System.dll)

Syntax

Visual Basic (Declaration)

Public Sub Stop

Visual Basic (Usage)

Dim instance As Stopwatch

instance.Stop()

public void Stop()

Visual C++

public:
void Stop()

JScript

public function Stop()

Remarks

In a typical Stopwatch scenario, you call the Start method, then eventually call the Stop method, and then you check elapsed time using the Elapsed property.

The Stop method ends the current time interval measurement. Stopping a Stopwatch that is not running does not change the timer state or reset the elapsed time properties.

When a Stopwatch instance measures more than one interval, the Stop method is equivalent to pausing the elapsed time measurement. A subsequent call to Start resumes measuring time from the current elapsed time value. Use the Reset method to clear the cumulative elapsed time in a Stopwatch instance.

Examples

The following example demonstrates how to use the Stop method to stop a timer that measures the execution time of an application.

Class Program

    Shared Sub Main(ByVal args() As String)
        Dim stopWatch As New Stopwatch()
        stopWatch.Start()
        Thread.Sleep(10000)
        stopWatch.Stop()
        ' Get the elapsed time as a TimeSpan value.
        Dim ts As TimeSpan = stopWatch.Elapsed

        ' Format and display the TimeSpan value.
        Dim elapsedTime As String = String.Format("{0:00}:{1:00}:{2:00}.{3:00}", ts.Hours, ts.Minutes, ts.Seconds, ts.Milliseconds / 10)
        Console.WriteLine(elapsedTime, "RunTime")

    End Sub 'Main
End Class 'Program

using System;
using System.Diagnostics;
using System.Threading;
class Program
{
    static void Main(string[] args)
    {
        Stopwatch stopWatch = new Stopwatch();
        stopWatch.Start();
        Thread.Sleep(10000);
        stopWatch.Stop();
        // Get the elapsed time as a TimeSpan value.
        TimeSpan ts = stopWatch.Elapsed;

        // Format and display the TimeSpan value.
        string elapsedTime = String.Format("{0:00}:{1:00}:{2:00}.{3:00}",
            ts.Hours, ts.Minutes, ts.Seconds,
            ts.Milliseconds / 10);
        Console.WriteLine(elapsedTime, "RunTime");
    }
