Accessing Cookies
You can gain access to the cookies associated with an HTTP response through the Cookies property defined by HttpWebResponse Cookies contain information that is stored by a browser They consist of name/value pairs, and they facilitate certain types of web access The Cookies property is defined like this: public CookieCollection Cookies { get; set; } CookieCollection implements ICollection and IEnumerable and can be used like any other collection (See 24) It has an indexer that allows a cookie to be obtained by specifying its index or its name CookieCollection stores objects of type Cookie Cookie defines several properties that give you access to the various pieces of information associated with a cookie The two that we will use here are Name and Value, which are defined like this: public string Name { get; set; } public string Value { get; set; }

The name of the cookie is contained in Name, and its value is found in Value To obtain a list of the cookies associated with a response, you must supply a cookie container with the request For this purpose, HttpWebRequest defines the property CookieContainer, shown here: public CookieContainer CookieContainer { get; set; } CookieContainer provides various fields, properties, and methods that let you store cookies By default, this property is null To use cookies, you must set it equal to an instance of the CookieContainer class For many applications, you won t need to work with the CookieContainer property directly Instead, you will use the CookieCollection obtained from the response CookieContainer simply provides the underlying storage mechanism for the cookies The following program displays the names and values of the cookies associated with the URI specified on the command line Remember, not all websites use cookies, so you might have to try a few until you find one that does
/* Examine Cookies To see what cookies a website uses, specify its name on the command line For example, if you call this program CookieDemo, then CookieDemo http://msncom displays the cookies associated with msncom */ using System; using SystemNet; class CookieDemo { static void Main(string[] args) { if(argsLength != 1) { ConsoleWriteLine("Usage: CookieDemo <uri>"); return ; } // Create a WebRequest to the specified URI HttpWebRequest req = (HttpWebRequest) WebRequestCreate(args[0]); // Get an empty cookie container reqCookieContainer = new CookieContainer(); // Send the request and return the response HttpWebResponse resp = (HttpWebResponse) reqGetResponse(); // Display the cookies ConsoleWriteLine("Number of cookies: " + respCookiesCount); ConsoleWriteLine("{0,-20}{1}", "Name", "Value");
