範例

以下範例展示了回應中回傳的 cookie 屬性。 完整範例請參見 Cookie 課程主題。

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

using (var response = (HttpWebResponse) request.GetResponse())
{
    // Print the properties of each cookie.
    foreach (Cookie cook in response.Cookies)
    {
        Console.WriteLine("Cookie:");
        Console.WriteLine($"{cook.Name} = {cook.Value}");
        Console.WriteLine($"Domain: {cook.Domain}");
        Console.WriteLine($"Path: {cook.Path}");
        Console.WriteLine($"Port: {cook.Port}");
        Console.WriteLine($"Secure: {cook.Secure}");

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

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

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

    Using response As HttpWebResponse = request.GetResponse()
        ' Print the properties of each cookie.
        For Each cook As Cookie In response.Cookies
            Console.WriteLine("Cookie:")
            Console.WriteLine($"{cook.Name} = {cook.Value}")
            Console.WriteLine($"Domain: {cook.Domain}")
            Console.WriteLine($"Path: {cook.Path}")
            Console.WriteLine($"Port: {cook.Port}")
            Console.WriteLine($"Secure: {cook.Secure}")

            Console.WriteLine($"When issued: {cook.TimeStamp}")
            Console.WriteLine($"Expires: {cook.Expires} (expired? {cook.Expired})")
            Console.WriteLine($"Don't save: {cook.Discard}")
            Console.WriteLine($"Comment: {cook.Comment}")
            Console.WriteLine($"Uri for comments: {cook.CommentUri}")
            Console.WriteLine($"Version: RFC {If(cook.Version = 1, 2109, 2965)}")

            ' Show the string representation of the cookie.
            Console.WriteLine($"String: {cook}")
        Next
    End Using

備註

將屬性設定 Expires 為 會 DateTime.MinValue 變成 session cookie，這是它的預設值。

Kind的屬性Expires用來判斷 Cookie 是否被設定為 DateTimeKind.LocalDateTimeKind.Utc或 。 若 Kind 屬性設為 DateTimeKind.Unspecified，則 Utc 假設 。
