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 Value of a Cookie must not be null. If a null value is assigned to this property, it's replaced with an empty string.

Semicolons and commas are reserved characters that cannot be used in the value of this property. Assigning invalid characters to this property doesn't throw an exception; but when you try to add this Cookie to a CookieContainer instance with the Add method, the operation will fail and throw an exception.
