有没有说每种方法需要花费多长时间的工具? [英] Any tool that says how long each method takes to run?

问题描述

我的程序的某些部分运行缓慢.我想知道是否有我可以使用的工具，例如，它可以告诉我可以正常运行methodA()花费了100ms，等等……或类似的有用信息.

some parts of my program are way slow. and I was wondering if there is tool that i can use and for example it can tell me ok running methodA() took 100ms , etc ...or so useful info similar to that.

推荐答案

System.Diagnostics命名空间提供了一个有用的类，称为

The System.Diagnostics namespace offers a helpful class called Stopwatch, which can be used to time parts of your code (think of it as a "poor man's profiler").

这是您将如何使用它:

Stopwatch stopwatch = new Stopwatch();
stopwatch.Start(); // Start timing

// This is what we want to time
DoSomethingWeSuspectIsSlow();

stopwatch.Stop();
Console.WriteLine("It took {0} ms.", stopwatch.ElapsedMilliseconds);
