1、扩展HtmlHelper类方法ShowPageNavigate

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 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 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 href='{0}?pageIndex={1}&pageSize={2}'>{3}</a> ", redirectTo, currentPage, pageSize, currentPage); } else {//一般页处理 output.AppendFormat("<a 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 href='{0}?pageIndex={1}&pageSize={2}'>下一页</a> ", redirectTo, currentPage + 1, pageSize); } output.Append(" "); if (currentPage != totalPages) { output.AppendFormat("<a 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

public ActionResult Index(int? pageSize, int? pageIndex) { int pageIndex1 = pageIndex ?? 1; int pageSize1 = pageSize ?? 5; int count = 0; //从数据库在取得数据，并返回总记录数 var temp = newsSer.LoadPageEntities(c => true, c => c.id, false, pageSize1, pageIndex1, out count); PagerInfo pager = new PagerInfo(); pager.CurrentPageIndex = pageIndex1; pager.PageSize = pageSize1; pager.RecordCount = count; PagerQuery<PagerInfo, IQueryable<news>> query = new PagerQuery<PagerInfo, IQueryable<news>>(pager, temp); return View(query); }

4、View里的部分代码

<tbody> @foreach (var item in Model.EntityList) { <tr> <td> <input name="ids[]" type="checkbox" value="" /> </td> <td> @item.author </td> <td> @item.title </td> <td> @item.ctime </td> <td> @Html.ActionLink("编辑", "Edit", new { id = item.id }) | @Html.ActionLink("删除", "Delete", new { id = item.id }) </td> </tr> } @*分页*@ <tr> <td colspan="5" align="center"> <span> @Html.ShowPageNavigate(Model.Pager.CurrentPageIndex, Model.Pager.PageSize, Model.Pager.RecordCount) </span> </td> </tr> </tbody>

5、添加一些样式

.paginator { font: 12px Arial, Helvetica, sans-serif; padding: 10px 20px 10px 0; margin: 0px auto; } .paginator a { border: solid 1px #ccc; color: #0063dc; cursor: pointer; text-decoration: none; } .paginator a:visited { padding: 1px 6px; border: solid 1px #ddd; background: #fff; text-decoration: none; } .paginator .cpb { border: 1px solid #F50; font-weight: 700; color: #F50; background-color: #ffeee5; } .paginator a:hover { border: solid 1px #F50; color: #f60; text-decoration: none; } .paginator a, .paginator a:visited, .paginator .cpb, .paginator a:hover { float: left; height: 16px; line-height: 16px; min-width: 10px; _width: 10px; margin-right: 5px; text-align: center; white-space: nowrap; font-size: 12px; font-family: Arial,SimSun; padding: 0 3px; } .paginator label { display:block; float:left; }

6.总结

这个案例简单实现了在MVC中快速分页，其实很多开源的项目中都有相关的HtmlHepler的扩展函数，其中也不乏带有分页的扩展，例如著名的开源商城项目nopCommerce，其中有就一个HtmlExtensions.cs扩展类，里面就有关于分页的扩展，人家写的可是相当专业哦，有兴趣的可以研究一下。
