c# - c# opennetcf RegistryHelper.SaveHiveBasedKey

Question

我正在尝试找出从 Windows Mobile 6.1 设备上备份整个注册表的最佳方法。我发现 OPENNETCF RegistryHelper 类据说可以保存基于蜂巢的密钥？

有人可以先帮我弄清楚这是否是最好的方法吗？

以下是我尝试使用并不断收到错误“无法生成注册表文件”的代码

private void button1_Click(object sender, EventArgs e)
        {
            RegistryKey Key = Registry.LocalMachine.OpenSubKey(@"System\StorageManager\Profiles\SDMMC");
            string outputkey = @"\Storage Card\key.reg";

            SaveHiveBasedKey(Key, outputkey);
        }


        public static void SaveHiveBasedKey(Microsoft.Win32.RegistryKey keyToSave, string destinationPath)
        {
            RegistryHelper.SaveHiveBasedKey(keyToSave, destinationPath);
        }

异常详情：

显然 Windows Mobile 使用基于 Ram 的注册表。

 private void button1_Click(object sender, EventArgs e)
        {

           string outputkey = @"\key.dat";

            //save registry to dat file
           SaveRamBasedRegistry(outputkey);
            //Restore registry file
           RestoreRamBasedRegistry(outputkey);
        }



        public static void SaveRamBasedRegistry(string destinationPath)
        {
            RegistryHelper.SaveRamBasedRegistry(destinationPath);
        }

        public static void RestoreRamBasedRegistry(string destinationPath)
        {
            RegistryHelper.RestoreRamBasedRegistry(destinationPath);
        }
