原文缺点:

构造函数只能是public的,导致可能由开发人员的失误引发多个Instance

改进:用反射调用private的构造函数。

Code



    public class Singleton<T>

    {



        public static T Instance

        {

            get { return SingletonCreator.instance; }

        }

        class SingletonCreator

        {

            internal static readonly T instance = (T)Activator.CreateInstance(typeof(T), true);

        }

    }

    public class Singleton<T>
    {
        internal static readonly T instance = (T)Activator.CreateInstance(typeof(T), true);
        public static T Instance
        {
            get { return instance; }
        }
    }
