public static HtmlString ShowPageNavigate( this HtmlHelper htmlHelper, int currentPage, int pageSize, int totalCount) { var redirectTo = htmlHelper.ViewContext.RequestContext.HttpContext.Request.Url.AbsolutePath; pageSize = pageSize == 0 ? 3 : pageSize; var totalPages = Math.Max((totalCount + pageSize - 1) / pageSize, 1); //总页数 var output = new StringBuilder(); if (totalPages > 1) { output.AppendFormat( "<a class='pageLink' href='{0}?pageIndex=1&pageSize={1}'>首页</a> " , redirectTo, pageSize); if (currentPage > 1) { //处理上一页的连接 output.AppendFormat( "<a class='pageLink' href='{0}?pageIndex={1}&pageSize={2}'>上一页</a> " , redirectTo, 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,前面5个,后面5个 if ((currentPage + i - currint) >= 1 && (currentPage + i - currint) <= totalPages) { if (currint == i) { //当前页处理 output.AppendFormat( "<a class='cpb' href='{0}?pageIndex={1}&pageSize={2}'>{3}</a> " , redirectTo, currentPage, pageSize, currentPage); } else { //一般页处理 output.AppendFormat( "<a class='pageLink' href='{0}?pageIndex={1}&pageSize={2}'>{3}</a> " , redirectTo, currentPage + i - currint, pageSize, currentPage + i - currint); } } output.Append( " " ); } if (currentPage < totalPages) { //处理下一页的链接 output.AppendFormat( "<a class='pageLink' href='{0}?pageIndex={1}&pageSize={2}'>下一页</a> " , redirectTo, currentPage + 1, pageSize); } output.Append( " " ); if (currentPage != totalPages) { output.AppendFormat( "<a class='pageLink' href='{0}?pageIndex={1}&pageSize={2}'>末页</a> " , redirectTo, totalPages, pageSize); } output.Append( " " ); } output.AppendFormat( "<label>第{0}页 / 共{1}页</label>" , currentPage, totalPages); //这个统计加不加都行 return new HtmlString(output.ToString()); } |
2、添加公共类PagerInfo,PageQuery

public class PagerInfo { public int RecordCount { get ; set ; } public int CurrentPageIndex { get ; set ; } public int PageSize { get ; set ; } } public class PagerQuery<TPager, TEntityList> { public PagerQuery(TPager pager, TEntityList entityList) { this .Pager = pager; this .EntityList = entityList; } public TPager Pager { get ; set ; } public TEntityList EntityList { get ; set ; } } |
3、然后在Controller里面添加Action
