The returned Stopwatch instance is stopped, and the elapsed time property of the instance is zero.

Use the Start method to begin measuring elapsed time with the new Stopwatch instance. Use the StartNew method to initialize a new Stopwatch instance and immediately start it.

The following example initializes a Stopwatch instance within a simple class constructor. This code example is part of a larger example provided for the Stopwatch class.

Dim stopWatch As StopWatch
Dim captureLap As Boolean

Public Sub New()

    MyBase.New()
    stopwatch = New StopWatch()
    captureLap = False
    InitializeComponent()

End Sub

private Stopwatch stopWatch;
private Boolean captureLap;

public FormMain()
{
    stopWatch = new Stopwatch();
    captureLap = false;

    InitializeComponent();
}

private:
   Stopwatch^ stopWatch;
   Boolean captureLap;

public:
   FormMain()
   {
      stopWatch = gcnew Stopwatch;
      captureLap = false;
      InitializeComponent();
   }

private Stopwatch stopWatch;
private Boolean captureLap;

public FormMain()
{
    stopWatch = new Stopwatch();
    captureLap = new Boolean(false);

    InitializeComponent();
} //FormMain
