注：該程序的啟動項設置到HKEY_Current_User 下，推薦。如果想改在HKEY_LOCAL_MACHINE，只需將CurrentUser改為LocalMachine，即

// 添加到 當前登陸用戶的 注冊表啟動項
RegistryKey RKey = Registry.CurrentUser.CreateSubKey(@"SOFTWARE\Microsoft\Windows\CurrentVersion\Run");
RKey.SetValue("AppName", @"C:\AppName.exe");

// 添加到 所有用戶的 注冊表啟動項
RegistryKey RKey = Registry.LocalMachine.CreateSubKey(@"SOFTWARE\Microsoft\Windows\CurrentVersion\Run");
RKey.SetValue("AppName", @"C:\AppName.exe");
