ASP.NET 从xml读出数据时的分页方法

public string GetPage(int page, int pages, string url)
        {
            if (pages == 0)
            {
                pages = 1;
            }
            string sb0 = "";
            int n1 = 0, n2 = 0;
            n1 = page - 5 <= 0 ? 1 : page - 5;
            n2 = page + 5 > pages ? pages : page + 5;
            if (n2 <= 9)
                n2 = 10;
            if (n2 > pages)
                n2 = pages;
            if (n2 - n1 < 9)
                n1 = n2 - 9 < 1 ? 1 : n2 - 9;
            sb0 += "　<a href=\"" + url + 1 + ".html\">首页</a>　";
            sb0 += "<a href=\"" + url + (page - 1 <= 0 ? 1 : page - 1)
                + ".html\">上一页</a>　";
            //判断是否是当前页
            for (; n1 <= n2; n1++)
