FormsAuthenticationTicket.Expiration Property

Gets the local date and time at which the forms-authentication ticket expires.

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

member Expiration : DateTime

Property Value

Type: System.DateTime
The DateTime at which the forms-authentication ticket expires.

If the FormsAuthenticationTicket is created using the FormsAuthenticationTicket(String, Boolean, Int32) constructor that does not supply a parameter for an expiration date and time, the Expiration property returns a value based on the current local date and time plus the value of the timeout parameter supplied to the constructor.

If the FormsAuthenticationTicket was created using a constructor that takes an expiration parameter, the Expiration property returns the value supplied to the expiration parameter.

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


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.

No code example is currently available or this language may not be supported.
