FormsAuthenticationTicket.IssueDate Property

Gets the local date and time at which the forms-authentication ticket was originally issued.

Namespace:  System.Web.Security
Assembly:  System.Web (in System.Web.dll)

public DateTime IssueDate { get; }

Property Value

Type: System.DateTime
The DateTime when the forms-authentication ticket was originally issued.

The IssueDate property represents the local date and time when the forms-authentication ticket was issued. The RenewTicketIfOld method uses the IssueDate property value to determine whether the Expiration date and time of a forms-authentication ticket needs to be renewed and also uses the IssueDate property value to determine the new Expiration date and time. When a ticket is renewed, the IssueDate property is updated to the local date and time.

The following code example displays the property values of the FormsAuthenticationTicket for the current logged-on user.

NoteNote:

If there is no logged-on user, the Identity property will be null and you will receive a compiler exception when attempting to cast the Identity property as a FormsIdentity object.
