Obtaining a cookie value from a logged in user on my website

[chopin]

I am trying to obtain the values of cookies from a particular website. The problem is, when I run the following code, it only loops through 4 of 10 cookie values present. Furthermore, the values are turning up as deleted: Reference

 
HttpWebRequest Request = (HttpWebRequest)WebRequest.Create("http://www.mysite.com");
Request.CookieContainer = new CookieContainer();
HttpWebResponse Response = (HttpWebResponse)Request.GetResponse();
 
foreach (Cookie cook in Response.Cookies)
       {                          
           Console.WriteLine("{0} = {1}", cook.Name, cook.Value);           
       }
 

Then I came across this code, which states it will loop through every cookie value and obtain its values: Reference

 
int loop1, loop2;         
       HttpCookieCollection MyCookieColl;
       HttpCookie MyCookie;
       MyCookieColl = Request.Cookies;
 
       String[] arr1 = MyCookieColl.AllKeys; 
       for (loop1 = 0; loop1 < arr1.Length; loop1++)
       {
           MyCookie = MyCookieColl[arr1[loop1]];          
           String[] arr2 = MyCookie.Values.AllKeys;
       }
 

The problem with the above, I can't seem to find a reference to "Request". I am using the libraries "using System.Net and
using System.Web", so I am unsure why Request is not being recognized.

My goal is to retrieve one cookie value so that when a user from my website logs in, my C# application will recognize that user.

Thanks for any help!

Try System.Web.HttpContext.Current.Request

I tried using this line here:

MyCookieColl = System.Web.HttpContext.Current.Request.Cookies;
 

Unfortunately, upon executing that line of code, it prematurely opened my form, and terminated the program. I'm not sure how to proceed in obtaining the cookie values.

Quick question, is this an ASP.NET Web Application or a WinForms application?

[chopin]

This is WinForms. I am developing an executable standalone program that will connect directly to my website's MySql database.

I've done some more investigating, and it appears that this line of code is deleting my cookie values, which is the cause for my problem:

HttpWebResponse Response = HttpWebResponse)Request.GetResponse();

I'm at a loss at what to do, it seems like the code in my first codeblock example is the correct way to accomplish what I need, the only problem being the above line deletes the values of the cookies I need.

Maybe this will help clarify what I am trying to do. The equivalent code in PHP to obtain a cookie value is:

$_COOKIE['cookie_name']

The above will output a cookie value if that cookie exists. That's it! Is there an equivalent function in C#?

[chopin]

I've actually figured out how to do this by utilizing PHP instead. PHP has a built in function that can capture a cookie value by name, called $_COOKIE['cookie_name']. When a PHP page is loaded, I execute MySQL insert commands to input temp data into a table. C# will execute the PHP page executing the PHP commands which will insert the cookie value into a table when the C# program is loaded. Since C# can grab information from a MySQL database, this is a valid solution. Here is the code that will launch the script:

System.Diagnostics.Process.Start("www.example.com/script.php");

Then C# will read the values from the temp table, storing the cookie values into a public static variable. My program will now recognize a username based on that cookie variable during the duration the program is opened.

I don't know of any other way at the moment to capture a cookie value, at least natively in a C# WinForms application. But the above solution is 100% accurate and works well.
