Examples

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

HttpWebRequest^ request = dynamic_cast<HttpWebRequest^>(WebRequest::Create( args[ 1 ] ));
request->CookieContainer = gcnew 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 = safe_cast<Cookie^>(myEnum->Current);
   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 ? (String^)"2109" : "2965" );
   
   // Show the string representation of the cookie.
   Console::WriteLine( "String: {0}", cook );
   
}

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

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.
