You can use the following method to store a string value in cookie using C#.net 4.0

public static void StoreCookie(string name, string valueToStore)
{
var cookie = new HttpCookie(name) {Value = valueToStore, Expires = DateTime.Now.AddYears(1)};
HttpContext.Current.Response.Cookies.Add(cookie);
}

Here classes like "HttpCookie" and "HttpContext" needs to be used in order to access cookies from a class library.
