Introduction
Sometimes
you may need to find out how much time a piece of code takes in
execution. This is very important when an application is slow. By using
this approach, you may find out what code takes how much time.
Platform
----------
.net 2.0/3.0/3.5
Language :
------------
C#
What
this code will do?
-------------------------------
Code will
measure how much time particular code statements takes to execute.
Implementation
----------------------
First
of all all, import this name space.
using System.Diagnostics;
Now we are using StopWatch class to measure the time
taken by the code.
This is how the UI looks like. Download the
attached project.
Most of the code is commented in this project so you can understand easily.
private void btnGetExecutionTime_Click(object sender, EventArgs e)
{
//First Create the instance of Stopwatch Class
Stopwatch sw = new Stopwatch();
// Start The StopWatch ...From 000
sw.Start();
for (int i = 0; i <= 1000; i++)
{
}
//Stop the Timer
sw.Stop();
//Writing Execution Time in label
string ExecutionTimeTaken = string.Format("Minutes :{0}\nSeconds :{1}\n Mili seconds :{2}", sw.Elapsed.Minutes, sw.Elapsed.Seconds, sw.Elapsed.TotalMilliseconds);
label1.Text = ExecutionTimeTaken;
}
Now whatever code you write between Start and Stop methods, that you can find out using Elapsed.
Now, you can use StopWatch to check other code. Just Reset the StopWatch using Reset method.
sw.Reset();
Another approach for measuring code Execution time is to Note Down the DateTime.Now before the execution and after the
Execution but StopWatch Approach will be more accurate than this DateTime.Now Approach.
