public void set_Expires (DateTime value)

public function get Expires () : DateTime

public function set Expires (value : DateTime)

Eigenschaftenwert

Das Ablaufdatum und die Ablaufzeit für das Cookie als DateTime-Instanz.

Hinweise

Wenn die Expires-Eigenschaft auf MinValue festgelegt wird, wird in der Standardeinstellung ein Sitzungs-Cookie erstellt.

Beispiel

Im folgenden Beispiel werden die Eigenschaften der Cookies angezeigt, die als Antwort zurückgeben wurden. Das vollständige Beispiel finden Sie unter dem Thema zur Cookie-Klasse.

Dim request As HttpWebRequest = CType(WebRequest.Create(args(0)), HttpWebRequest)
request.CookieContainer = New CookieContainer()

Dim response As HttpWebResponse = CType(request.GetResponse(), HttpWebResponse)



' Print the properties of each cookie.
Dim cook As Cookie
For Each cook In  response.Cookies
    Console.WriteLine("Cookie:")
    Console.WriteLine("{0} = {1}", cook.Name, cook.Value)
    Console.WriteLine("Domain: {0}", cook.Domain)
    Console.WriteLine("Path: {0}", cook.Path)
    Console.WriteLine("Port: {0}", cook.Port)
    Console.WriteLine("Secure: {0}", cook.Secure)
    
    Console.WriteLine("When issued: {0}", cook.TimeStamp)
    Console.WriteLine("Expires: {0} (expired? {1})", cook.Expires, cook.Expired)
    Console.WriteLine("Don't save: {0}", cook.Discard)
    Console.WriteLine("Comment: {0}", cook.Comment)
    Console.WriteLine("Uri for comments: {0}", cook.CommentUri)
    Console.WriteLine("Version: RFC {0}", IIf(cook.Version = 1, "2109", "2965"))
