[DllImport("urlmon.dll", CharSet = CharSet.Ansi)] private static extern int UrlMkSetSessionOption( int dwOption, string pBuffer, int dwBufferLength, int dwReserved); const int URLMON_OPTION_USERAGENT = 0x10000001; const int URLMON_OPTION_USERAGENT_REFRESH = 0x10000002; public void ChangeUserAgent() { string ua = "Googlebot/2.1 (+http://www.google.com/bot.html)"; UrlMkSetSessionOption(URLMON_OPTION_USERAGENT_REFRESH, null, 0, 0); UrlMkSetSessionOption(URLMON_OPTION_USERAGENT, ua, ua.Length, 0); }
