Create Read (Get) Cookie values in Asp.net using C#, VB.NET with Example

Sep 22, 2015
Introduction

Here I will explain how to create and read cookie values in
asp.net using c#, vb.net with example or write and get cookie values in asp.net using c#, vb.net with example. By using Response.Cookies and Request.Cookies properties we can create and read or get cookie values in asp.net using c#, vb.net.

Description:
  
In previous articles I explained Asp.net mvc project example with demo, Bind specific columns of datatable to datagridview in c#,
bind gridview using jquery json method in asp.net, show multiple markers in google map from database in asp.net and many articles relating to gridview, asp.net, c#,vb.net and jQuery. Now I will explain how to create, read or get or write cookie values in asp.net using c#, vb.net with example.

To create, read or get cookies in asp.net open your aspx page and write the following code


<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Create, Write and Read Cookies in Asp.net using C#, VB.NET</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:Button ID="btnCreate" runat="server" Text="Create Cookies" onclick="btnCreate_Click" />
<asp:Button ID="btnGet" runat="server" Text ="Get Cookie Values" onclick="btnGet_Click" /><br /><br />
<asp:Label ID="lblResult" runat="server"/>
</div>
</form>
</body>
</html>

After completion of aspx page add following namespaces in codebehind

C# Code


using System;
using System.Web;

After completion of adding namespaces you need to write the code like as shown below


protected void btnCreate_Click(object sender, EventArgs e)
{
Response.Cookies["UserId"].Value = "1234";
Response.Cookies["UserId"].Expires = DateTime.Now.AddDays(1);
Response.Cookies["UserName"].Value = "Suresh";
Response.Cookies["UserName"].Expires = DateTime.Now.AddDays(1);
lblResult.Text = "Cookie Values Created Successfully";
}
protected void btnGet_Click(object sender, EventArgs e)
{
string userid = Request.Cookies["UserId"].Value;
string username = Request.Cookies["UserName"].Value;
lblResult.Text = "<b>Cookie Values</b> : UserId: " + userid + ", UserName: " + username;
}

VB.NET Code


Imports System.Web

Partial Class VBCode
Inherits System.Web.UI.Page
Protected Sub Page_Load(sender As Object, e As EventArgs)
End Sub
Protected Sub btnCreate_Click(ByVal sender As Object, ByVal e As EventArgs)
Response.Cookies("UserId").Value = "1234"
Response.Cookies("UserId").Expires = DateTime.Now.AddDays(1)
Response.Cookies("UserName").Value = "Suresh"
Response.Cookies("UserName").Expires = DateTime.Now.AddDays(1)
lblResult.Text = "Cookie Values Created Successfully"
End Sub
Protected Sub btnGet_Click(ByVal sender As Object, ByVal e As EventArgs)
Dim userid As String = Request.Cookies("UserId").Value
Dim username As String = Request.Cookies("UserName").Value
lblResult.Text = Convert.ToString((Convert.ToString("<b>Cookie Values</b> : UserId: ") & userid) + ", UserName: ") & username
End Sub
End Class
