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 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

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>【本文来自：由专业的香港高防服务器转发】;> 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 class="checkBox">
        <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 class="">
    <td colspan="5" align="center" class="paginator">
      <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。
