本文主要做了一個(gè)HtmHelper類的分頁(yè)擴(kuò)展函數(shù)，方便在視圖中調(diào)用，有需要的朋友可以參考一下，希望對(duì)大家有所幫助。

1、擴(kuò)展HtmlHelper類方法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); //總頁(yè)數(shù)

  var output = new StringBuilder();

  if (totalPages > 1)

  {

    output.AppendFormat("<a class='pageLink' href='{0}?pageIndex=1&pageSize={1}'>首頁(yè)</a> ", redirectTo, pageSize);

    if (currentPage > 1)

    {//處理上一頁(yè)的連接

      output.AppendFormat("<a class='pageLink' href='{0}?pageIndex={1}&pageSize={2}'>上一頁(yè)</a> ", redirectTo, currentPage - 1, pageSize);

    }

    output.Append(" ");

    int currint = 5;

    for (int i = 0; i <= 10; i++)

    {//一共最多顯示10個(gè)頁(yè)碼，前面5個(gè)，后面5個(gè)

      if ((currentPage + i - currint) >= 1 && (currentPage + i - currint) <= totalPages)

      {

        if (currint == i)

        {//當(dāng)前頁(yè)處理              

          output.AppendFormat("<a class='cpb' href='{0}?pageIndex={1}&pageSize={2}'>{3}</a> ", redirectTo, currentPage, pageSize, currentPage);

        }

        else

        {//一般頁(yè)處理

          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)

    {//處理下一頁(yè)的鏈接

      output.AppendFormat("<a class='pageLink' href='{0}?pageIndex={1}&pageSize={2}'>下一頁(yè)</a> ", redirectTo, currentPage + 1, pageSize);

    }

    output.Append(" ");

    if (currentPage != totalPages)

    {

      output.AppendFormat("<a class='pageLink' href='{0}?pageIndex={1}&pageSize={2}'>末頁(yè)</a> ", redirectTo, totalPages, pageSize);

    }

    output.Append(" ");

  }

  output.AppendFormat("<label>第{0}頁(yè) / 共{1}頁(yè)</label>", currentPage, totalPages);//這個(gè)統(tǒng)計(jì)加不加都行

  return new HtmlString(output.ToString());

}

2、添加公共類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;

  //從數(shù)據(jù)庫(kù)在取得數(shù)據(jù)，并返回總記錄數(shù)

  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里的部分代碼

<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("編輯", "Edit", new { id = item.id }) |

        @Html.ActionLink("刪除", "Delete", new { id = item.id })

      </td>

    </tr>

  }

  @*分頁(yè)*@

  <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、添加一些樣式

.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.總結(jié)

這個(gè)案例簡(jiǎn)單實(shí)現(xiàn)了在MVC中快速分頁(yè)，其實(shí)很多開(kāi)源的項(xiàng)目中都有相關(guān)的HtmlHepler的擴(kuò)展函數(shù)，其中也不乏帶有分頁(yè)的擴(kuò)展，例如著名的開(kāi)源商城項(xiàng)目nopCommerce，其中有就一個(gè)HtmlExtensions.cs擴(kuò)展類，里面就有關(guān)于分頁(yè)的擴(kuò)展，人家寫(xiě)的可是相當(dāng)專業(yè)哦，有興趣的可以研究一下。
