Is there a way to read/write the cookies that a WebBrowser control uses?

 Here is sample from [link][1]
 >   public static class WinInetHelper
        {
            public static bool SupressCookiePersist()
            {
                // 3 = INTERNET_SUPPRESS_COOKIE_PERSIST
                // 81 = INTERNET_OPTION_SUPPRESS_BEHAVIOR
                return SetOption(81, 3);
            }
    
            public static bool EndBrowserSession()
            {
                // 42 = INTERNET_OPTION_END_BROWSER_SESSION
                return SetOption(42, null);
            }
            static bool SetOption(int settingCode, int? option)
            {
                IntPtr optionPtr = IntPtr.Zero;
                int size = 0;
                if (option.HasValue)
                {
                    size = sizeof(int);
                    optionPtr = Marshal.AllocCoTaskMem(size);
                    Marshal.WriteInt32(optionPtr, option.Value);
                }
    
                bool success = InternetSetOption(0, settingCode, optionPtr, size);
    
                if (optionPtr != IntPtr.Zero) Marshal.Release(optionPtr);
                return success;
            }
    
            [System.Runtime.InteropServices.DllImport("wininet.dll", CharSet = CharSet.Auto, SetLastError = true)]
            private static extern bool InternetSetOption(
            int hInternet,
            int dwOption,
            IntPtr lpBuffer,
            int dwBufferLength
            );
        }
