C＃确定方法的执行时间 [英] C# Determine execution Time of a method

问题描述

我想检查执行特定功能所需的时间，以便在程序中添加准确的时间延迟......

我之前尝试写过这个在我的职能之后：

I want to check the amount of time it takes for a specific function to be performed ,so that I will add accurate time delay on my program...
I tried to write this before and after my function:

public static String GetTimestamp(this DateTime value)
      {
          return value.ToString(mmssffff);
      }

然后我计算了两个结果之间的差异，我得到350.I不知道它是微秒还是毫秒...



你知道结果的意义吗？（350）

你还有另外一个想法吗？

谢谢！

Then I calculated the difference between both results, and I get 350.I dont know if it microseconds or milliseconds...

Do you know the meaning of the result?(350)
Do you have another idea to do this?
Thanks!

推荐答案

为什么不写这样的东西：

Why don't you write something like this:

DateTime start = DateTime.Now; //Start time
DoFoo(); //Execute your method
DateTime end = DateTime.Now;   //End time

TimeSpan timeDifference = end - start; //Time span between start and end = the time span needed to execute your method
int difference_Miliseconds = (int)span.TotalMilliseconds; //Gives you the time needed to execute the method in miliseconds (= time between start and end in miliseconds)

解决方案1中显示的方法不是最准确的。最准确的时间由类 System.Diagnostics.Stopwatch 提供：

http://msdn.microsoft.com/en-us/library/system.diagnostics.stopwatch%28v=vs。 110％29.aspx [ ^ ]。



您可以通过检查这两个静态字段找出时间分辨率：

http://msdn.microsoft .com / zh-cn / library / system.diagnostics.stopwatch.frequency（v = vs.110）.aspx [ ^ ]，

http://msdn.microsoft.com/en-us/library/system.diagnostics.stopwatch.ishighresolution（V = vs.110）的.aspx [< a href =http://msdn.microsoft.com/en-us/library/system.diagnostics.stopwatch.ishighresolution(v=vs.110).aspx\"target =_ blanktitle =New Window> ^ ]。

The method shown in Solution 1 is not the most accurate. The most accurate timing is provided by the class System.Diagnostics.Stopwatch:
http://msdn.microsoft.com/en-us/library/system.diagnostics.stopwatch%28v=vs.110%29.aspx[^].

You can find out time resolution provided by checking these two static fields:
http://msdn.microsoft.com/en-us/library/system.diagnostics.stopwatch.frequency(v=vs.110).aspx[^],
http://msdn.microsoft.com/en-us/library/system.diagnostics.stopwatch.ishighresolution(v=vs.110).aspx[^].
