How can I create a single cookie and save multiple pairs key/values to it?

Question

Hi!

In ASP.NET MVC, how can I create a single cookie and save multplie values to it?

Thanks!!

Answer 1

var cookie = new HttpCookie();
cookie.Values["FirstKey"] = value1;
cookie.Values["SecondKey"] = value2;

or a shortcut:

cookie["ThirdKey"] = value3;

HttpCookie.Values is a NameValueCollection, a class that appears in many places in ASP.NET MVC. Read this for a good tutorial on how to use it to its full potential.

Answer 2

This problem can be rephrased as: "How can I store multiple values in a single string?"

It's up to you to come up with a system. If the values are simples numbers or strings, use a separator like a ";" and then split later.
