Stopwatch 建構函式

定義

命名空間:

System.Diagnostics

組件:

System.Runtime.dll

來源:

Stopwatch.cs

初始化 Stopwatch 類別的新執行個體。

public:
 Stopwatch();

public Stopwatch ();

Public Sub New ()

範例

下列範例會使用簡單的類別建構函式來初始化 Stopwatch 實例。

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("RunTime " + elapsedTime);
    }
}

Imports System.Diagnostics
Imports System.Threading


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( "RunTime " + elapsedTime)

    End Sub
End Class

備註

傳回的 Stopwatch 實例已停止，而實例的經過時間屬性為零。

Start使用方法來開始使用新的 Stopwatch 實例來測量經過的時間。 StartNew使用 方法來初始化新的Stopwatch實例，並立即啟動它。
