.net 获取浏览器Cookie(包括HttpOnly)实例分享

一、接口文件

代码如下:
using System;
using System.ComponentModel;
using System.Net;
using System.Runtime.InteropServices;
using System.Security;
using System.Security.Permissions;
using System.Text;

namespace CookieHandler
{
    internal sealed class INativeMethods
    {
        #region enums

        public enum ErrorFlags
        {
            ERROR_INSUFFICIENT_BUFFER = 122,
            ERROR_INVALID_PARAMETER = 87,
            ERROR_NO_MORE_ITEMS = 259
        }

        public enum InternetFlags
        {
            INTERNET_COOKIE_HTTPONLY = 8192, //Requires IE 8 or higher     
            INTERNET_COOKIE_THIRD_PARTY = 131072,
            INTERNET_FLAG_RESTRICTED_ZONE = 16
        }

        #endregion

        #region DLL Imports

        [SuppressUnmanagedCodeSecurity, SecurityCritical, DllImport("wininet.dll", EntryPoint = "InternetGetCookieExW", CharSet = CharSet.Unicode, SetLastError = true, ExactSpelling = true)]
        internal static extern bool InternetGetCookieEx([In] string Url, [In] string cookieName, [Out] StringBuilder cookieData, [In, Out] ref uint pchCookieData, uint flags, IntPtr reserved);

        #endregion
    }
}

二、获取cookie类

代码如下:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Net;
using System.Runtime.InteropServices;
using System.Security;
using System.Security.Permissions;
using System.Text;

namespace CookieHandler
{
    /// <SUMMARY></SUMMARY>
    /// 取得WebBrowser的完整Cookie。
    /// 因为默认的webBrowser1.Document.Cookie取不到HttpOnly的Cookie
    /// IE7不兼容，IE8可以，其它未知
    ///
    public class FullWebBrowserCookie
    {
        public static Dictionary<string, string> GetCookieList(Uri uri, bool throwIfNoCookie)
        {
            Dictionary<string, string> dict = new Dictionary<string, string>();
