Introduction
Here I will explain how to count number of visitors to
website in asp.net using C#
and VB.NET or find or get number of visitors for a website in asp.net
using C# and VB.NET.
Description
In previous articles I explained Asp.net Interview questions, Export Gridview data to PDF, Send values from one page to another page using QueryString,
Joins in SQL Server, Highlight Gridview records based on search and many
articles relating to Gridview,
SQL, jQuery,asp.net,
C#,VB.NET.
Now I will explain how to count number of visitors to website in asp.net
using C# and VB.NET.
To get number of visits for website we
need to use methods in Global.asax
file for that first add Global.asax
file in your application
Open Visual Studio -à Create New Website
-à Right click on
Solution Explorer -à Select Add New Item
-à Select Global
Application Class file and click OK
Now open Global.asax file and write the code like as shown below
void Application_Start(object
sender, EventArgs e)
{
// Code that runs on application
startup
Application["NoOfVisitors"]
= 0;
}
void Session_Start(object
sender, EventArgs e)
{
// Code that runs when a new
session is started
Application.Lock();
Application["NoOfVisitors"]
= (int)Application["NoOfVisitors"]
+ 1;
Application.UnLock();
}
|
In above code Application_Start event will raise only once when application starts
and Session_Start event will raise for every postback operation if
you want to know more about it check this What
is Global.asax file and uses of it
Now open your aspx page and write
the following code
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1"
runat="server">
<table>
<tr>
<td>
<b>No
of Visits:</b>
</td>
<td>
<asp:Label ID="lblCount" runat="server" ForeColor="Red" />
</td>
</tr>
</table>
</form>
</body>
</html>
|
Now in code behind add the following namespaces
C#
Code
using System;
|
After that add below code in
code behind
protected void
Page_Load(object sender, EventArgs e)
{
lblCount.Text = Application["NoOfVisitors"].ToString();
}
|
VB.NET
Code
Partial Class VbCode
Inherits System.Web.UI.Page
Protected Sub
Page_Load(sender As Object,
e As EventArgs)
Handles Me.Load
lblCount.Text = Application("NoOfVisitors").ToString()
End Sub
End Class
|

Note: Here we are using Application level variable in Global.asax file because of that if application restart automatically the values will be reset

How to get visitor number on particular url of website

Hi suresh,
as per you aritacle you said that "Session_Start event will raise for every postback operation". but i don't think so that every post back raise session start event. kindly correct my if i am wrong
Error: Object reference not set to an instance of an object.
lblCount.Text = Application["NoOfVisitors"].ToString();
what if the is restarted
what if i want to get the count at the end of the day..is there any specific interval after which the count is reset to 0.Pl mention in detail of everything.This all sounds half knowledge which is dangerous.
Remove Application["NoOfVisitors"] = 0; from Application_Start
And In Session_Start put below code
if(Application["NoOfVisitors"] == null)
{Application["NoOfVisitors"]=0;}
Application.Lock();
Application["NoOfVisitors"] = (int)Application["NoOfVisitors"] + 1;
Application.UnLock();
Yes its very smooth an clean code but when i stop my site its again counts from 0,
is there any solution ?
Thanks
