c# opennetcf RegistryHelper.SaveHiveBasedKey

Question

我正在尝试找出备份windows mobile 6.1设备的整个注册表的最佳方法。我发现OPENNETCF RegistryHelper类，据说会保存一个基于hive的键?

谁能先帮我弄清楚这是否是最好的方法?

下面是我试图使用的代码，并不断得到错误"无法生成注册表文件"

private void button1_Click(object sender, EventArgs e)
        {
            RegistryKey Key = Registry.LocalMachine.OpenSubKey(@"SystemStorageManagerProfilesSDMMC");
            string outputkey = @"Storage Cardkey.reg";
            SaveHiveBasedKey(Key, outputkey);
        }

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

异常细节:

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);
        }
