如何轻松地计算一个C＃代码块？ [英] How to easily time a block of C# code?

问题描述

我需要一个简单的方法（如果可能，紧凑）执行一个C＃块，同时计数时间。类似于此C ++代码的代码：

I need a simple way (and compact if possible) to execute a block of C# while counting time. Something similar to this C++ code:

elapsed = time_call([&] 
   {
      for_each (a.begin(), a.end(), [&](int n) {
         results1.push_back(make_tuple(n, fibonacci(n)));
      });
   });   

其中time_call是：

where time_call is:

// Calls the provided work function and returns the number of milliseconds 
// that it takes to call that function.
template <class Function>
__int64 time_call(Function&& f)
{
   __int64 begin = GetTickCount();
   f();
   return GetTickCount() - begin;
}

我知道秒表的方式...更紧凑吗？

I know the stopwatch way... anything more compact ?

推荐答案

TimeSpan TimeAction(Action blockingAction)
{
    Stopwatch stopWatch = System.Diagnostics.Stopwatch.StartNew();
    blockingAction();
    stopWatch.Stop();
    return stopWatch.Elapsed;
}

用法：

var elapsed = TimeAction(() =>
    {
        //Code to time
    });

根据您的示例代码code> GetTickCount ），您可能希望返回 ElapsedTicks 而不是 Elapsed 。

Based on your sample code (and usage of GetTickCount) you might want to return ElapsedTicks instead of Elapsed.
