[转][C#]单例模式之懒加载

private static ILog log = LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType.Name);
public static UserInfo Instance { get { return Linstance.Value; } }
private static readonly Lazy<UserInfo> Linstance = new Lazy<UserInfo>(() => return new UserInfo(););

访问时直接访问 Instance 即可。
