64位系統，讀取時是要有區別的，寫入時沒有問題。這裡的代碼時通用的，已經內部判斷當前系統的位元。

使用方法

1             RegistryKey64 key = new DTPM.Util.Configs.RegistryKey64(RegistryHive.LocalMachine);2             key.OpenKey(@"SOFTWARE\XXX\XXX");3             string path = key.GetValue("ConfigPath") as string;4             key.RegistryKey.Close();
