IEnumerator与IEnumerable探讨 (续)

代码优先

    public class NewMyClass : IEnumerable, IEnumerator
    {
        private string[] Info;
        private int Index;
        public NewMyClass(int Size)
        {
            Index = -1;
            Info = new string[Size];
            for (int i = 0; i < Size; i++)
            {
                Info[i] = i.ToString();
            }
        }
        public object Current { get { return Info[Index]; } }
        public void Reset()
        {
            Index = -1;
        }
        public bool MoveNext()
        {
            Index++;
            return Index >= Info.Length ? false : true;
        }
        public IEnumerator GetEnumerator()
        {
            return (IEnumerator)this;
        }
    }

以上是结合后的代码
