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

'Declaration
Public ReadOnly Property Expired As Boolean
'Usage
Dim instance As FormsAuthenticationTicket
Dim value As Boolean

value = instance.Expired

/** @property */
public boolean get_Expired ()

public function get Expired () : boolean

Not applicable.

Property Value

true if the forms-authentication ticket has expired; otherwise, false.

The Expired property returns true if the Expiration date and time is less than the current local date and time; otherwise, the Expired property returns false.

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 a null reference (Nothing in Visual Basic) and you will receive a compiler exception when attempting to cast the Identity property as a FormsIdentity object.
