I click on the quick sort, sorting method is right but the elapsed time does not display, excuse me, what's the problem, please help

CodePudding user response:

Use a Stopwatch to time:

 var clock=System. Diagnostics. Stopwatch. StartNew (); 
//time-consuming operation,,, 
Var takes milliseconds=clock. ElapsedMilliseconds; 

CodePudding user response:

If it is for each of the sorting method consumes time, it must not use the timer control, timer control is at regular intervals to perform a task, should use the. NET built-in Stopwatch class,

 using System; 
Using System. Collections. Generic; 
Using System. Linq; 
Using System. The Text; 
Using System. The Threading. The Tasks; 

The namespace ConsoleApplication1 
{
Class Program 
{
The static void Main (string [] args) 
{
Int [] nums={3, 2, 1}; 

//start the time 
System. Diagnostics. Stopwatch watch=new System. Diagnostics. The Stopwatch (); 
Watch the Reset (); 
Watch. Start (); 

//stop timing 
SortMethodOne (nums); 
Watch. Stop (); 
Console. WriteLine (" methods used by one time is: {0} milliseconds ", watch. ElapsedMilliseconds); 

//to timing 
Watch. Restart (); 
SortMethodTwo (nums); 
Watch. Stop (); 
Console. WriteLine (" time is used for the method 2: "{0} milliseconds, watch. ElapsedMilliseconds); 
} 

The static void SortMethodOne (int [] nums) 
{
//a sorting method takes 3000 milliseconds 
System. Threading. Thread. Sleep (3000); 
} 

The static void SortMethodTwo (int [] nums) 
{
//sorting method 2 5000 milliseconds 
System. Threading. Thread. Sleep (5000); 
} 
} 
} 

CodePudding user response:

First of all, record the current time
And operating your order
Then write down the time



Then the time - the consumption of the current time is your time

Thank you very much, beginners, understand now, I try
