Cookie.Version Property

Gets or sets the version of HTTP state maintenance to which the cookie conforms.

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

Property Value

Type: System.Int32
The version of HTTP state maintenance to which the cookie conforms.
ExceptionCondition
ArgumentOutOfRangeException

The value specified for a version is not allowed.

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.

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());
}
