登錄檔可以用來進行儲存一些程式的資訊，例如使用者的許可權、或者某些值等，可以根據個人需要進行儲存和刪減。
當前登錄檔主目錄：
引用包 Wesky.Net.OpenTools 1.0.5或者以上版本
操作演示：
建立登錄檔項
設定登錄檔值
讀取登錄檔值
刪除登錄檔值
刪除登錄檔項
操作演示程式碼
IRegistryManager registryManager = new RegistryManager();
// 建立登錄檔項
// registryManager.CreateKey(RegistryRoot.CurrentUser, @"Wesky\MyApp");
// 設定登錄檔值
// registryManager.SetValue(RegistryRoot.CurrentUser, @"Wesky\MyApp", "MyValue", "Hello, Registry!");
// 讀取登錄檔值
// var value = registryManager.GetValue(RegistryRoot.CurrentUser, @"Wesky\MyApp", "MyValue");
// Console.WriteLine($"讀取到的登錄檔值:{value}");
// 刪除登錄檔值
// registryManager.DeleteValue(RegistryRoot.CurrentUser, @"Wesky\MyApp", "MyValue");
// 刪除登錄檔項
registryManager.DeleteKey(RegistryRoot.CurrentUser, @"Wesky\MyApp");
Console.WriteLine("Over");
Console.ReadKey();
