How to use cookie in asp.net using C#?.Is there any sample for cookies?

In order to handle a cookie in your system you should aware of 2 things:

1 - How to create them

2 - How to delete them

So, first in order to create a cookie you have 2 variable must be defined as they are the cookie name and the duration of the cookie before it expired

• In order to create a cookie it looks like this one

////SET THE COOKIE////

Response.Cookies["test"].Value = UserName.Text ;

Response.Cookies["test"].Expires = DateTime.Now.AddYears(30);

Where test is the cookie name and the username.text is the textbox that will be used to define the cookies information.

* In order to delete a cookie use this

Response.Cookies["test"].Expires = DateTime.Now.AddYears(-30);

* In order to check whether the cookie is found or not and retrieve the cookies information use this

////check to see if cookie presented////

if (Request.Cookies["test"] == null)

TextBox2.Text = "No cookie found";

else

TextBox2 .Text = Request.Cookies["test"].Value;

////END check to see if cookie presented////

Hi buddy,

Here's a tutorial that shows you how to use cookies in ASP .NET. I'm not going to explain the role of cookies in web applications or cover any other theoretical aspect of cookies. There are many (similar) ways to handle cookies in ASP .NET. I'm only going to show you one of the ways, my way. Oh, and we're going to use C#, although the code can be adapted to Visual Basic .NET easily.

How to create a cookie.

Here's a new cookie named cakes.

We created the cookie but there are no keys with values in it, so for now it's useless. So let's add some:

We also need to add the cookie to the cookie collection (consider it a cookie jar ):

How to get the value stored in a cookie.

Here's how to get the keys and values stored in a cookie:

The output to using this with the previous created cookie is this: "aaa=favour&bbb=secret".



However, most of the time you'll want to get the value stored at a specific key. If we want to find the value stored at our bbb key, we use this:

That's all....
