Remarks

This class stores a collection of cookie objects associated with a client Web request.

You should always create a CookieCollection and add it to the request if you want to retrieve Cookie objects from the response.

Examples

The following example shows how to retrieve the CookieCollection from a response and write them to an isolated storage file.

' Get the response and write cookies to isolated storage. 
Private Sub ReadCallback(ByVal asynchronousResult As IAsyncResult)
    Dim request As HttpWebRequest = DirectCast(asynchronousResult.AsyncState,  _
        HttpWebRequest)
    Dim response As HttpWebResponse = _
    DirectCast(request.EndGetResponse(asynchronousResult), HttpWebResponse)
    Using isf As IsolatedStorageFile = IsolatedStorageFile.GetUserStoreForSite()
        Using isfs As IsolatedStorageFileStream = isf.OpenFile("CookieExCookies", _
            FileMode.OpenOrCreate, FileAccess.Write)
            Using sw As New StreamWriter(isfs)
                For Each cookieValue As Cookie In response.Cookies
                    sw.WriteLine("Cookie: " + cookieValue.ToString())
                Next
                sw.Close()
            End Using

        End Using
    End Using
End Sub
private void ReadCallback(IAsyncResult asynchronousResult)
{
    HttpWebRequest request = (HttpWebRequest)asynchronousResult.AsyncState;
    HttpWebResponse response = (HttpWebResponse)
        request.EndGetResponse(asynchronousResult);
    using (IsolatedStorageFile isf =
        IsolatedStorageFile.GetUserStoreForSite())
    {
        using (IsolatedStorageFileStream isfs = isf.OpenFile("CookieExCookies",
            FileMode.OpenOrCreate, FileAccess.Write))
        {
            using (StreamWriter sw = new StreamWriter(isfs))
            {
                foreach (Cookie cookieValue in response.Cookies)
                {
                    sw.WriteLine("Cookie: " + cookieValue.ToString());
                }
                sw.Close();
            }
        }

    }
}
