c# 分页代码控制生成分页html代码

在实际的开发中，网页列表中需要用到分页，以下代码用c#实现的前台页面的分页脚本，可以参考学习下。

 protected static string CreatePage(string urlFormat, int currentPage, int pageSize, int recordCount, out int totalPage)
        {
            string prevPage = string.Empty;
            string nextPage = string.Empty;
            string hostPageUri = urlFormat;
            StringBuilder sb = new StringBuilder(""); 

            totalPage = recordCount % pageSize == 0 ? recordCount / pageSize : recordCount / pageSize + 1;

            if (totalPage <= 1)
                return string.Empty;
            if (totalPage > 100)
                totalPage = 100;

            if (recordCount != 0)
            {
                sb.Append("<div class='page'>");

                if (currentPage < 1)
                {
                    currentPage = 1;
                }
                if (currentPage > totalPage)
                {
                    currentPage = totalPage;
                }

                int startCount = (currentPage + 3) > totalPage ? totalPage - 5 : currentPage - 2;
                int endCount = currentPage < 3 ? 6 : currentPage + 3;

                if (startCount < 1)
                {
                    startCount = 1;
                }

                if (endCount > totalPage)
                {
                    endCount = totalPage;
                }

                //首页
                if (endCount > 6)
                {
                    sb.AppendFormat("<a href=\"{0}\">首页</a>", hostPageUri + "p1/");
                }

                //上一页
                if (currentPage > 1)
                {
                    if (currentPage == 2)
                    {
                        sb.AppendFormat("<a href=\"{0}\">上一页</a>", hostPageUri + "p1/");
                    }
                    else
                    {
                        sb.AppendFormat("<a href=\"{0}\">上一页</a>", hostPageUri + "p" + (currentPage - 1).ToString() + "/");
                    }
                    prevPage = hostPageUri + "p" + (currentPage - 1).ToString() + "/";
                }

                //中间数字页码
                for (int i = startCount; i <= endCount; i++)
                {
                    if (i == currentPage)
                    {
                        sb.AppendFormat("<a href='javascript:;' class='active'>{0}</a>", i);
                        currentPage = i;
                    }
                    else
                    {
                        if (i > 5 && i == endCount && endCount < totalPage)
                        {
                            sb.Append("<span>...</span>");
                            sb.AppendFormat("<a href=\"{0}\" >{1}</a>", hostPageUri + "p" + totalPage.ToString() + "/", totalPage);
                        }
                        else
                        {
                            if (i == 1)
                            {
                                sb.AppendFormat("<a href=\"{0}\" >1</a>", hostPageUri + "p1/");
                            }
                            else
                            {
                                sb.AppendFormat("<a href=\"{0}\" >{1}</a>", hostPageUri + "p" + i.ToString() + "/" , i);
                            }
                        }
                    }
                }

                //下一页
                if (currentPage < totalPage)
                {
                    sb.AppendFormat("<a href=\"{0}\">下一页</a>", hostPageUri + "p" + (currentPage + 1) + "/");
                    nextPage = hostPageUri + "p" + (currentPage + 1).ToString() + "/";
                }

                //末页
                if (endCount < totalPage && totalPage > 1)
                {
                    sb.AppendFormat("<a href=\"{0}\">末页</a>", hostPageUri + "p" + totalPage.ToString() + "/");
                }

                //sb.AppendFormat("<span class=\"totalPage\">共{0}页，到第<input type=\"text\" name=\"PageIndex\" id=\"PageIndex\" class=\"pageInput\"/>页</span>", totalPage);
                sb.Append("<span class=\"totalPage\"> 到第<input type=\"text\" name=\"PageIndex\" id=\"PageIndex\" class=\"pageInput\"/>页</span>");
                sb.AppendFormat("<a href=\"javascript:;\" class=\"btn\" onclick=\"GoPage('{0}');\">GO</a>", hostPageUri);

                sb.Append("</div>");
            } 
            return sb.ToString(); 
        }

实现的效果如图所示
