Exemple #1

        {
            PagingRange range = new PagingRange();

            if (pageCount <= _rangeLength)
            {
                range.StartIndex  = 1;
                range.FinishIndex = pageCount;

                return(range);
            }

            int semiLength = (int)Math.Floor(_rangeLength / 2.0);

            range.StartIndex  = pageIndex - semiLength;
            range.FinishIndex = pageIndex + semiLength;

            if (range.StartIndex < 1)
            {
                range.FinishIndex -= range.StartIndex - 1;
                range.StartIndex   = 1;

                return(range);
            }

            if (range.FinishIndex > pageCount)
            {
                range.StartIndex -= range.FinishIndex - pageCount;
