 2             RegistryKey registryKey = Registry.LocalMachine.OpenSubKey(registrySubKey, true);
 3             if (registryKey == null)//没有则创建路径
 4             {
 5                 Registry.LocalMachine.CreateSubKey(registrySubKey);
 6                 registryKey = Registry.LocalMachine.OpenSubKey(registrySubKey, true);
 7             }
 8             //写入注册表
 9             registryKey.SetValue("Name", "zhangsan");
10             //读出注册表
