Create Cookie in MVC 3

asp.net, asp.net-mvc, asp.net-mvc-3

Solution

Cookies are created the same way as they are in plain old ASP.NET, you just need to access the `Response`.

        public ActionResult Login(string username, string password, bool rememberMe)
        {
            // validate username/password

            if (rememberMe)
            {
               HttpCookie cookie = new HttpCookie("RememberUsername", username);
               Response.Cookies.Add(cookie);
            }

            return View();

        }

However, if you're using Forms Auth, you can just make your FormsAuth ticket cookie persistent:

        public ActionResult Login(string username, string password, bool rememberMe)
        {
            // validate username/password

            FormsAuthentication.SetAuthCookie(username, rememberMe);

            return View();

        }

You can read cookies like this:

public ActionResult Index()
{
    var cookie = Request.Cookies["RememberUsername"];

    var username = cookie == null ? string.Empty : cookie.Value; // if the cookie is not present, 'cookie' will be null. I set the 'username' variable to an empty string if its missing; otherwise i use the cookie value

    // do what you wish with the cookie value

    return View();
}

If you are using Forms Authentication and the user is logged in, you can access their username like this:

public ActionResult Index()
{


    var username = User.Identity.IsAuthenticated ? User.Identity.Name : string.Empty;

    // do what you wish with user name

    return View();
}

It is possible to decrypt and read the contents of a ticket. You can even store small amounts of custom data in the ticket, if you need to. See this article for more info.
