FormsAuthenticationTicket(Int32, String, DateTime, DateTime, Boolean, String)	Initializes a new instance of the FormsAuthenticationTicket class with cookie name, version, expiration date, issue date, persistence, and user-specific data. The cookie path is set to the default value established in the application's configuration file.

FormsAuthenticationTicket(String, Boolean, Int32)

Initializes a new instance of the FormsAuthenticationTicket class using a cookie name and expiration information.

public:
 FormsAuthenticationTicket(System::String ^ name, bool isPersistent, int timeout);

public FormsAuthenticationTicket (string name, bool isPersistent, int timeout);

new System.Web.Security.FormsAuthenticationTicket : string * bool * int -> System.Web.Security.FormsAuthenticationTicket

Public Sub New (name As String, isPersistent As Boolean, timeout As Integer)

Parameters

name: String

The user name associated with the ticket.

isPersistent: Boolean

true if the ticket will be stored in a persistent cookie (saved across browser sessions); otherwise, false. If the ticket is stored in the URL, this value is ignored.

timeout: Int32

The time, in minutes, for which the authentication ticket is valid.

Remarks

The FormsAuthenticationTicket object created by this constructor will have a CookiePath value set to the value of the FormsCookiePath property, a Version value of 2, an IssueDate value of the current local date and time, a UserData value of an empty string (""), and an Expiration value that is set to the current local date and time plus the value of the timeout parameter.

Applies to

FormsAuthenticationTicket(Int32, String, DateTime, DateTime, Boolean, String)

Initializes a new instance of the FormsAuthenticationTicket class with cookie name, version, expiration date, issue date, persistence, and user-specific data. The cookie path is set to the default value established in the application's configuration file.

public:
 FormsAuthenticationTicket(int version, System::String ^ name, DateTime issueDate, DateTime expiration, bool isPersistent, System::String ^ userData);

public FormsAuthenticationTicket (int version, string name, DateTime issueDate, DateTime expiration, bool isPersistent, string userData);

new System.Web.Security.FormsAuthenticationTicket : int * string * DateTime * DateTime * bool * string -> System.Web.Security.FormsAuthenticationTicket

Public Sub New (version As Integer, name As String, issueDate As DateTime, expiration As DateTime, isPersistent As Boolean, userData As String)

Parameters

version: Int32

The version number of the ticket.

name: String

The user name associated with the ticket.

issueDate: DateTime

The local date and time at which the ticket was issued.

expiration: DateTime

The local date and time at which the ticket expires.

isPersistent: Boolean

true if the ticket will be stored in a persistent cookie (saved across browser sessions); otherwise, false. If the ticket is stored in the URL, this value is ignored.

userData: String

The user-specific data to be stored with the ticket.

Remarks

The FormsAuthenticationTicket object created by this constructor will have a CookiePath value set to the value of the FormsCookiePath.

Note

The userData parameter cannot be null.

Applies to

FormsAuthenticationTicket(Int32, String, DateTime, DateTime, Boolean, String, String)

Initializes a new instance of the FormsAuthenticationTicket class with cookie name, version, directory path, issue date, expiration date, persistence, and user-defined data.

public:
 FormsAuthenticationTicket(int version, System::String ^ name, DateTime issueDate, DateTime expiration, bool isPersistent, System::String ^ userData, System::String ^ cookiePath);

public FormsAuthenticationTicket (int version, string name, DateTime issueDate, DateTime expiration, bool isPersistent, string userData, string cookiePath);

new System.Web.Security.FormsAuthenticationTicket : int * string * DateTime * DateTime * bool * string * string -> System.Web.Security.FormsAuthenticationTicket

Public Sub New (version As Integer, name As String, issueDate As DateTime, expiration As DateTime, isPersistent As Boolean, userData As String, cookiePath As String)

Parameters

version: Int32

The version number of the ticket.

name: String

The user name associated with the ticket.

issueDate: DateTime

The local date and time at which the ticket was issued.

expiration: DateTime

The local date and time at which the ticket expires.

isPersistent: Boolean

true if the ticket will be stored in a persistent cookie (saved across browser sessions); otherwise, false. If the ticket is stored in the URL, this value is ignored.

userData: String

The user-specific data to be stored with the ticket.

cookiePath: String

The path for the ticket when stored in a cookie.

The following code example stores the result of the Encrypt method in a cookie using the FormsCookieName property and redirects the user to the URL returned from the GetRedirectUrl method.
