如何在HttpWebRequest中获取由“ Set-Cookie”设置的cookie？

Question

I was hoping the following code would yield a non-zero value:

var webRequest = (HttpWebRequest) WebRequest.Create(loginUrl);
var webResponse = (HttpWebResponse)webRequest.GetResponse();
Console.WriteLine(webResponse.Cookies.Count);

yet no cookies seem to show up in webRespone.Cookies . I'm positive the cookies are there, as I'm sniffing the data with Fiddler. This is the response I'm getting:

HTTP/1.1 200 OK
Cache-Control: private
Content-Type: text/html; charset=utf-8
Server: Microsoft-IIS/7.5
Set-Cookie: __Abc=Def; path=/; HttpOnly
PS-ResponseTime: 00:00:00.0624001
PS-Build: 2013-03-19-11-36-59
PS-Node: 02
Date: Tue, 19 Mar 2013 21:14:51 GMT
Content-Length: 57872

Does it have anything to do with the fact the cookie is HttpOnly ?

Edit

It's seems I can get them through HttpWebRequest 's CookieContainer which is certainly useful if I intend to proceed to a sequence of requests/responses. But why can't I access them the same through the HttpWebResponse.Cookies field, anyway?

Thanks

You're right, you'll need to hand the request an instance of CookieContainer and then reference that instance to see the cookies. Basically, HttpWebResponse does not directly expose cookies on the response that are marked as HttpOnly.
