Cookie.Expires Property

Gets or sets the expiration date and time for the Cookie as a DateTime.

Namespace:  System.Net
Assembly:  System (in System.dll)
public DateTime Expires { get; set; }

Property Value

Type: System.DateTime
The expiration date and time for the Cookie as a DateTime instance.

Setting the Expires property to MinValue makes this a session Cookie, which is its default value.

The following example displays the properties of cookies returned in a response. For the complete example, see the Cookie class topic.

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(args[0]);
request.CookieContainer = new CookieContainer();

HttpWebResponse response = (HttpWebResponse) request.GetResponse();



// Print the properties of each cookie. 
foreach (Cookie 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}" , cook.Version == 1 ? "2109" : "2965");

    // Show the string representation of the cookie.
    Console.WriteLine ("String: {0}", cook.ToString());
}
HttpWebRequest* request = dynamic_cast<HttpWebRequest*>(WebRequest::Create(args[1]));
request->CookieContainer = new CookieContainer();

HttpWebResponse* response = dynamic_cast<HttpWebResponse*> (request->GetResponse());
response->Cookies = request->CookieContainer->GetCookies(request->RequestUri);


// Print the properties of each cookie.
System::Collections::IEnumerator* myEnum = response->Cookies->GetEnumerator();
while (myEnum->MoveNext())
{
    Cookie* cook = __try_cast<Cookie*>(myEnum->Current);
    Console::WriteLine(S"Cookie:");
    Console::WriteLine(S"{0} = {1}", cook->Name, cook->Value);
    Console::WriteLine(S"Domain: {0}", cook->Domain);
    Console::WriteLine(S"Path: {0}", cook->Path);
    Console::WriteLine(S"Port: {0}", cook->Port);
    Console::WriteLine(S"Secure: {0}", __box(cook->Secure));

    Console::WriteLine(S"When issued: {0}", __box(cook->TimeStamp));
    Console::WriteLine(S"Expires: {0} (expired? {1})", __box(cook->Expires), __box(cook->Expired));
    Console::WriteLine(S"Don't save: {0}", __box(cook->Discard));    
    Console::WriteLine(S"Comment: {0}", cook->Comment);
    Console::WriteLine(S"Uri for comments: {0}", cook->CommentUri);
    Console::WriteLine(S"Version: RFC {0}" , cook->Version == 1 ? S"2109" : S"2965");

    // Show the string representation of the cookie.
    Console::WriteLine (S"String: {0}", cook);
}
