注册表可以用来进行存储一些程序的信息，例如用户的权限、或者某些值等，可以根据个人需要进行存储和删减。
当前注册表主目录：
引用包 Wesky.Net.OpenTools 1.0.5或者以上版本
操作演示：
创建注册表项
设置注册表值
读取注册表值
删除注册表值
删除注册表项
操作演示代码
IRegistryManager registryManager = new RegistryManager(); // 创建注册表项 // registryManager.CreateKey(RegistryRoot.CurrentUser, @"WeskyMyApp"); // 设置注册表值 // registryManager.SetValue(RegistryRoot.CurrentUser, @"WeskyMyApp", "MyValue", "Hello, Registry!"); // 读取注册表值 // var value = registryManager.GetValue(RegistryRoot.CurrentUser, @"WeskyMyApp", "MyValue"); // Console.WriteLine($"读取到的注册表值:{value}"); // 删除注册表值 // registryManager.DeleteValue(RegistryRoot.CurrentUser, @"WeskyMyApp", "MyValue"); // 删除注册表项 registryManager.DeleteKey(RegistryRoot.CurrentUser, @"WeskyMyApp"); Console.WriteLine("Over"); Console.ReadKey();
