如何在windows应用程序c＃中计算程序的执行时间？ [英] How to calculate the execution time of the program in windows application c#?

问题描述

我在c＃中实现了三种算法，我想根据执行时间比较这些算法，请给我在c＃windows窗口中比较这些算法的代码？我该怎么比较？我真的需要它

解决方案

你可以使用秒表 [ ^ ]为此。这样的事情：

  var  watch = Stopwatch.StartNew（） ; 
  //  您要衡量的代码来这里 
 watch.Stop （）; 
  var  elapsedMs = watch.ElapsedMilliseconds;

你的意思是什么？请解释一下？

请参阅：

http://msdn.microsoft.com/en-us/library/system.diagnostics.stopwatch.ishighresolution(v = vs.110）.aspx [ ^ ] ，

http： //msdn.microsoft.com/en-us/library/system.diagnostics.stopwatch.frequency(v=vs.110).aspx [ ^ ]。



调用这两个属性，你会看到。因此，在精确的时间内，使用双重属性

http://msdn.microsoft.com/en-us/library/system.timespan.totalseconds(v = vs.110）.aspx [ ^ ]，

http://msdn.microsoft.com/ en-us / library / system.timespan.totalminutes（v = vs.110）.aspx [ ^ ]，

http://msdn.microsoft.com/en-us/library/system.timespan.totalmilliseconds（v = VS .110）.aspx [ ^ ]，

http://msdn.microsoft.com/en-us/library/system.timespan.totalhours（v = vs.110） .aspx [ ^ ]，

http://msdn.microsoft.com/en-us/library/system.timespan.totaldays(v = vs.110）.aspx [ ^ ]，以获得适当的具有适当精度的小数值，而不是 int 属性秒，毫秒等，带有舍入错误。

I have a three algorithms implemented in c#, i want to compare these algorithm on the basis of the execution time, please give me the code that compare these algorithm in c# windows form?? an how can i compare it?? i really need it

解决方案

You can use Stopwatch [^]for this. Something like this:

var watch = Stopwatch.StartNew();
// the code that you want to measure comes here
watch.Stop();
var elapsedMs = watch.ElapsedMilliseconds;

Member 11063279 asked:

what did you mean? please explain?

Please see:
http://msdn.microsoft.com/en-us/library/system.diagnostics.stopwatch.ishighresolution(v=vs.110).aspx[^],
http://msdn.microsoft.com/en-us/library/system.diagnostics.stopwatch.frequency(v=vs.110).aspx[^].

Call these two properties and you will see. Therefore, for a precise time, use double properties
http://msdn.microsoft.com/en-us/library/system.timespan.totalseconds(v=vs.110).aspx[^],
http://msdn.microsoft.com/en-us/library/system.timespan.totalminutes(v=vs.110).aspx[^],
http://msdn.microsoft.com/en-us/library/system.timespan.totalmilliseconds(v=vs.110).aspx[^],
http://msdn.microsoft.com/en-us/library/system.timespan.totalhours(v=vs.110).aspx[^],
http://msdn.microsoft.com/en-us/library/system.timespan.totaldays(v=vs.110).aspx[^], to get proper fractional value with appropriate accuracy, instead of int properties Seconds, Milliseconds, etc., with their rounding errors.
