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
.
