【前言】

   最近小編在專案中需要通過Linq表示式實現資料的查詢，但是在介面顯示的時候需要進行分頁，接下來和大家分享一下，這個功能點是怎麼實現的。

HTML

<table id="dg" class="easyui-datagrid"title="累積稽核"  style="width:75%;height:500px;"url="/AccumulateEvaluation/LoadPage" data-options="singleSelect:true,pagination:true,fitColumns:true,sortName:'itemid',sortOrder:'desc'" > 
            <thead>
                <tr>
                    <th data-options="field:'departmentName'" style="width: 8px" align="center">上傳的型別</th>
                    <th data-options="field:'accumulateStates'" style="text-align: right; width: 8px" align="center">處理結果</th>
                    <th data-options="field:'accumulateDescription'" style="width: 10px" align="center">描述</th>
                    <th data-options="field:'userName'" style="text-align: right; width: 10px" align="center">上傳者</th>
                    <th data-options="field:'userID'" style="width: 10px" align="center" hidden>上傳者ID</th>
                    <th data-options="field:'date'" style="width: 10px" align="center">上傳時間</th>
                    
            </tr>
         </thead>
    </table>
 

D層

public List<accumulateModel>  LoadPage(int pageSize, int pageIndex,out int total)
       {           

           //查詢總記錄.ToList();
           total = DBcontext.t_accumulate.Count();

          //分頁查詢t_accumulate
           List<accumulateModel> accumulatelist = new List<accumulateModel>();

           accumulatelist = (from a in DBcontext.t_accumulate
                             join d in DBcontext.t_department on a.departmentID equals d.departmentID
                             join u in DBcontext.t_user on a.userID equals u.userID
                             where (a.accumulateStates.Contains("未稽核"))
                             select new accumulateModel()
                             {
                                 accumulateDescription = a.accumulateDescription,
                                 accumulateStates = a.accumulateStates,
                                 departmentName = d.departmentName,
                                 userName = u.userName,
                                 userID=u.userID,
                                 date =a.date
                             }).OrderBy(p => p.date).Skip((pageIndex - 1) * pageSize).Take(pageSize).ToList();
           return accumulatelist;

       }
