/// <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++) {//一共最多显示10个页码 if ((currentPage + i - currint) >= 1 && (currentPage + i - currint) <= totalPages) {//处理当前页面的前面5个,后面5个 if (currentPage == (currentPage + i - currint)) { //处理当前页 output.AppendFormat("<a class='cpb' href='{0}?pageIndex={1}&pageSize={2}'>{3}</a>", redirecTo, currentPage, pageSize, currentPage); } else {//处理其它页 output.AppendFormat("<a class='pageLink' href='{0}?pageIndex={1}&pageSize={2}'>{3}</a>", redirecTo, currentPage + i - currint, pageSize, currentPage + i - currint); } } output.Append(" "); } if (currentPage < totalPages) { //处理下一页 output.AppendFormat("<a class='pageLink' href='{0}?pageIndex={1}&pageSize={2}'>下一页</a>",redirecTo,currentPage+1,pageSize); } if (currentPage != totalPages) { //处理末页 output.AppendFormat("<a class='pageLink' href='{0}?pageIndex={1}&pageSize={2}'>末页</a>",redirecTo,totalPages,pageSize); } output.Append(" "); } output.AppendFormat("第{0}页/共{1}页", currentPage, totalPages);//统计 return output.ToString(); }
