C# - Count Number of Visitors in Website using in C#, VB.NET

Nov 26, 2013

Here I will explain how to count number of visitors to website in using C# and VB.NET or find or get number of visitors for a website in using C# and VB.NET.


In previous articles I explained 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,, C#,VB.NET. Now I will explain how to count number of visitors to website in 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["NoOfVisitors"] = (int)Application["NoOfVisitors"] + 1;
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="">
<head runat="server">
<form id="form1" runat="server">
<b>No of Visits:</b>
<asp:Label ID="lblCount" runat="server" ForeColor="Red" />
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();

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

Download Sample Code Attached

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

Error: Object reference not set to an instance of an object.

Unknown said...

Unknown said...

what if i want to get the count at the end of the 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"] = (int)Application["NoOfVisitors"] + 1;

Unknown said...

Yes its very smooth an clean code but when i stop my site its again counts from 0,
is there any solution ?
