C#版 分页导航条

封装成静态方法，方便使用，代码如下：

/// <summary>
        /// 分页控件
        /// </summary>
        /// <param name="pageSize">分页大小</param>
        /// <param name="currentPage">当前页</param>
        /// <param name="totalCount">总记录数</param>
        /// <returns></returns>
        public static string ShowPageNavigate(int pageSize, int currentPage, int totalCount)
        {
            string redirecTo="";//跳转的页面
            //如果没有pageSize，默认设置为3
            pageSize = pageSize == 0 ? 3 : pageSize;
            int totalPages = Math.Max((totalCount + pageSize - 1) / pageSize, 1);//总分页数
            var output = new StringBuilder();
            if (totalPages > 1)
            {
                if (currentPage != 1)
                {//处理首页链接                    
                    output.AppendFormat("<a class='pageLink' href='{0}?pageIndex=1&pageSize={1}'>首页</a>", redirecTo, pageSize);
                }
                if (currentPage > 1)
                { //处理上一页
                    output.AppendFormat("<a class='pageLink' href='{0}?pageIndex={1}&pageSize={2}'>上一页</a>", redirecTo, currentPage - 1, pageSize);

                output.Append(" ");
                int currint = 5;
                for (int i = 0; i < 10; i++)

                    if ((currentPage + i - currint) >= 1 && (currentPage + i - currint) <= totalPages)
