篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了c#注册表对象映射相关的知识，希望对你有一定的参考价值。
用于快捷保存与读取注册表，为对应的对象
示例
[RegistryRoot(Name = "superAcxxxxx")] public class Abc : IRegistry { public string Name { get; set; } public int Age { get; set; } }
保存
Abc a = new Abc { Name = "mokeyish", Age = 100 }; RegistryKey register = RegistryKey.OpenBaseKey(RegistryHive.CurrentUser, Environment.Is64BitOperatingSystem ? RegistryView.Registry64 : RegistryView.Registry32); RegistryKey writeKey=register.CreateSubKey("SOFTWARE"); if (writeKey != null) { a.Save(writeKey); writeKey.Dispose(); } register.Dispose();
读取
Abc a=new Abc(); RegistryKey register = RegistryKey.OpenBaseKey(RegistryHive.CurrentUser, Environment.Is64BitOperatingSystem ? RegistryView.Registry64 : RegistryView.Registry32); RegistryKey writeKey=register.OpenSubKey("SOFTWARE"); if (writeKey != null) { a.Read(writeKey); writeKey.Dispose(); } register.Dispose();
