Change the user data in FormsAuthenticationTicket programmatically

问题

I am using the FormsAuthenticationTicket and place the data and passing the data across all the pages. and it will work if we are not changing any data.

So, now if I want to change the data and pass it for the cookie and encrypt then how to change the data programmatically.

Please give me the solution for changing the data in HttpCookie programmatically.

This is an example of how I modify an already-issued forms auth ticket:

HttpCookie cookie = FormsAuthentication.GetAuthCookie(Username, true);
var ticket = FormsAuthentication.Decrypt(cookie.Value);

// Store UserData inside the Forms Ticket with all the attributes
// in sync with the web.config
var newticket = new FormsAuthenticationTicket(ticket.Version,
                                              ticket.Name,
                                              ticket.IssueDate,
                                              ticket.Expiration,
                                              true, // always persistent
                                              "User Data",
                                              ticket.CookiePath);

// Encrypt the ticket and store it in the cookie
cookie.Value = FormsAuthentication.Encrypt(newticket);
cookie.Expires = newticket.Expiration.AddHours(24);
this.Context.Response.Cookies.Set(cookie);
