/// 获得分页Html代码
/// </summary>
/// <param name="totalNum">总条数</param>
/// <param name="pageSize">每页显示的总条数</param>
/// <param name="currentPage">当前页</param>
/// <param name="reUrl">生成的url地址连接</param>
/// <returns>分页Html代码</returns>
public static string PageGotoList(int totalNum, int pageSize, int currentPage, string reUrl)
{
//计算总页数
int totalPage = totalNum / pageSize;
//如果超额页数+1
if (totalNum % pageSize != 0)
{
totalPage = totalPage + 1;
}
//如果当前页小于1将赋值为1
if (currentPage < 1) currentPage = 1;
//如果当前页大于总页数将赋值为总页数
if (currentPage > totalPage) currentPage = totalPage;
int NextPage = 0;
int PrevPage = 0;
//int PageStart = 0;
//int PageEnd = 0;
StringBuilder PageStr = new StringBuilder();

//PageStart = (currentPage + 5) > totalPage ? totalPage - 9 : currentPage - 4;//中间页起始序号
//PageEnd = currentPage < 5 ? 10 : currentPage + 5;//中间页终止序号
//if (PageStart < 1) { PageStart = 1; } //为了避免输出的时候产生负数，设置如果小于1就从序号1开始
//if (totalPage < PageEnd) { PageEnd = totalPage; }//页码+5的可能性就会产生最终输出序号大于总页码，那么就要将其控制在页码数之内
PageStr.AppendFormat(currentPage < totalPage ? "<a href="#{0}&PageNo={1}" class="b">下一页</a>" : "下一页", reUrl, NextPage.ToString());
PageStr.AppendFormat(currentPage > 1 ? " <a href="#{0}&PageNo={1}" class="b">上一页</a> <a href="#{0}&PageNo=1" class="b">首页</a>" : " 上一页 首页", reUrl, PrevPage.ToString(), totalPage.ToString());
