Stopwatch 构造函数

定义

命名空间:

System.Diagnostics

程序集:

System.Runtime.dll

Source:

Stopwatch.cs

初始化 Stopwatch 类的新实例。

public:
 Stopwatch();

public Stopwatch ();

Public Sub New ()

示例

以下示例使用简单的类构造函数初始化 Stopwatch 实例。

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

注解

返回的 Stopwatch 实例已停止，该实例的已用时间属性为零。

Start使用 方法开始测量新Stopwatch实例的已用时间。 StartNew使用 方法初始化新Stopwatch实例并立即启动它。
