在.NET高分辨率定时器 [英] High resolution timer in .NET
本文介绍了在.NET高分辨率定时器的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我希望做我的code一些基本的分析,却发现DateTime.Now在C#中只有约16毫秒的分辨率。必须有更好的时间保持构造,我还没有发现。
I'd like to do some basic profiling of my code, but found that the DateTime.Now in C# only have a resolution of about 16 ms. There must be better time keeping constructs that I haven't yet found.
推荐答案
下面是code样本位时的操作:
Here is a sample bit of code to time an operation:
Dim sw As New Stopwatch()
sw.Start()
//Insert Code To Time
sw.Stop()
Dim ms As Long = sw.ElapsedMilliseconds
Console.WriteLine("Total Seconds Elapsed: " & ms / 1000)
编辑:
和整齐的事情是,它可以恢复为好。
And the neat thing is that it can resume as well.
Stopwatch sw = new Stopwatch();
foreach(MyStuff stuff in _listOfMyStuff)
{
sw.Start();
stuff.DoCoolCalculation();
sw.Stop();
}
Console.WriteLine("Total calculation time: {0}", sw.Elapsed);

The Stopwatch class will use a high-resolution counter if one is available on your system.
