Examples

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

C#
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}");
    }
}

Remarks

The default value for the Version property is 0, complying with the original Netscape specification. If the value is explicitly set to 1, then this Cookie must conform to RFC 2109. Note that if a Cookie was created automatically by receiving a Set-Cookie2 HTTP response header, the conformance is set to RFC 2965.

An attempt to set the Version property to a value less than zero will throw an exception.
