如何从 Internet Explorer 获取与 cookie 关联的过期日期和标志？

我可以得到 cookie 的值互联网获取Cookie http://msdn.microsoft.com/en-us/library/windows/desktop/aa384710%28v=vs.85%29.aspx or InternetGetCookieEx http://msdn.microsoft.com/en-us/library/windows/desktop/aa384714%28v=vs.85%29.aspx。但我想获取过期日期和标志（httpOnly，安全）以及数据。我找不到允许我在 Internet Explorer（BHO）中执行此操作的函数（C++ 或 C#）。

using System.Net;
using System;

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(<your URL>);
request.CookieContainer = new CookieContainer();

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

// Print the properties of each cookie.
foreach (Cookie cook in response.Cookies)
{
  Console.WriteLine("Cookie:");
  Console.WriteLine("{0} = {1}", cook.Name, cook.Value);
  Console.WriteLine("Domain: {0}", cook.Domain);
  Console.WriteLine("Path: {0}", cook.Path);
  Console.WriteLine("Port: {0}", cook.Port);
  Console.WriteLine("Secure: {0}", cook.Secure);

  Console.WriteLine("When issued: {0}", cook.TimeStamp);
  Console.WriteLine("Expires: {0} (expired? {1})", cook.Expires, cook.Expired);
  Console.WriteLine("Don't save: {0}", cook.Discard);    
  Console.WriteLine("Comment: {0}", cook.Comment);
  Console.WriteLine("Uri for comments: {0}", cook.CommentUri);
  Console.WriteLine("Version: RFC {0}" , cook.Version == 1 ? "2109" : "2965");

  // Show the string representation of the cookie.
  Console.WriteLine ("String: {0}", cook.ToString());
}
