关于数据源翻页

最近项目要对采集的数据图谱进行翻页，然而数据源类型不一致，不过其本质都是集合.

 public class MyPage<T>
    {
        /// <summary>
        /// 当前显示页
        /// </summary>
        private int _currentIndex;

        public int CurrentIndex
        {
            get
            {
                return _currentIndex;
            }
        }

        /// <summary>
        /// 比较数据源
        /// </summary>
        private ICollection<T> _dataSource;

        /// <summary>
        /// 数据总条数
        /// </summary>
        private int _total;

        public bool IsBigOne
        {
            get
            {
                return _dataSource.Count > 1;
            }
        }

        /// <summary>
        /// 初始化
        /// </summary>
        /// <param name="data"></param>
        public ComParisonPage(ICollection<T> data)
        {
            if (data != null)
            {
                _dataSource = data;
                _currentIndex = 0;

            }
        }

        /// <summary>
        /// 上一页
        /// </summary>
        public void Prev()
        {
            _currentIndex -= 1;
            if (_currentIndex < 0) _currentIndex = 0;
        }

        /// <summary>
        /// 下一页
        /// </summary>
        public void Next()
        {
            _currentIndex += 1;
            if (_currentIndex >= _dataSource.Count - 1) _currentIndex = _dataSource.Count - 1;
        }

        public T Current
        {
            get
            {
                return _dataSource.ElementAt(_currentIndex);
            }
        }


        public bool IsTop
        {
            get
            {
                return _currentIndex == 0;
            }
        }

        public bool IsBottom
        {
            get
            {
                return _currentIndex >= _dataSource.Count - 1;
            }
        }
    }

下面就可以实例这个类了：

      private Page<KeyValuePair<double, Spectrum>> P1 = null;

      private Page<model> p2 = null;
