Split Cookie in headers

I have the following Cookies in headers

Cookie: ASP.NET_SessionId=cm3bg4muwin1vmbovc1esjy3; host=SCANDICWEB101; ieAlertDisplay=true; scandic_lb_cookie=1702298890.0.0000; s_sv_sid=110733906247;

This is my code to get the first one

var sessionId = webResponse.Headers["Set-Cookie"].Split(';')
                   .First(s => s.StartsWith("ASP.NET_SessionId="));

I tried to get the host, scandic_lb_cookie and the rest as well, but I couldnt figure out a way to do it, could you suggest me some ideas to get them?

You should be able to iterate over cookie properties. Check HttpWebResponse Cookie property and How To: Get and Set Cookies on MSDN. There is no need to do any complex string operation.

    private void ReadCookies()
    {
        HttpWebRequest request = (HttpWebRequest) WebRequest.Create("http://gmail.com");
        request.CookieContainer = new CookieContainer();

        HttpWebResponse response = (HttpWebResponse)request.GetResponse();

        //Console.WriteLine(response.Headers.ToString());
        //Console.WriteLine(response.StatusCode.GetHashCode());

        CookieCollection IncomingCookies = response.Cookies;
        Console.WriteLine("Listing out {0} cookies received.", IncomingCookies.Count);
        foreach(Cookie cookie in IncomingCookies)
        {
            Console.WriteLine("{0} = {1}", cookie.Name, cookie.Value);
        }
        return;
    }

Possibly there are faster solutions, but following should work:

string source = cookie.Substring(8); // remove the "Cookie: "
var parts = source.Split(';')
                .Where(i => i.Contains("=")) // filter out empty values
                .Select(i => i.Trim().Split('=')) // trim to remove leading blank
                .Select(i => new { Name = i.First(), Value = i.Last() });

Then you can use them like:

foreach(var val in parts)
{
    string name = val.Name;
    string value = val.Value;
}

Or if you like it as a Dictionary<string, string>:

string source = coockie.Substring(8); // remove the "Cookie: "
var parts = source.Split(';')
                .Where(i => i.Contains("="))
                .Select(i => i.Trim().Split('='))
                .ToDictionary(i => i.First(), i => i.Last());

and then

string host = parts["host"];

See complete and working LINQPad example HERE.

What about this:

var sessionId = webResponse.Headers["Set-Cookie"]
    .Split(';')
    .Where(s => s.StartsWith("scandic_lb_cookie="));
