設置成這樣子
我是用網上找的dotras的代碼來建立vpn連接的。。英語水平不太好，不會把數據加密選線那裡改為可選加密

VPN建立連接時候怎麼設置屬性：安全：數據加密：可選加密
##
RasEntry entry = RasEntry.CreateVpnEntry(updateVPNname, updateVPNip,RasVpnStrategy.L2tpOnly,RasDevice.GetDeviceByName("(L2TP)", RasDeviceType.Vpn));
entry.EncryptionType = RasEncryptionType.Optional;//少了這個,這個就是設置屬性：安全：數據加密：可選加密
allUsersPhoneBook.Entries.Add(entry);
dialer.EntryName = updateVPNname;
dialer.PhoneBookPath = RasPhoneBook.GetPhoneBookPath(RasPhoneBookType.AllUsers); ##
