使用MVC 5 ADO.NET进行排序和分页

Question

我有以下代码：

1. 模型

    public int ManufactureID { get; set; } public string Manufacture { get; set; } public string ManufactureDescription { get; set; } public bool IsActive { get; set; } 

2. 控制者

    public ActionResult ManufactureIndex(string manufacture = "") { ManufactureRepository ManufactureRepo = new ManufactureRepository(); ModelState.Clear(); ViewBag.sManufacture = manufacture; return View(ManufactureRepo.ManufactureGetAll(manufacture)); } 

3. 资料库

    private SqlConnection con; //To Handle connection related activities private void Connection() { con = new SqlConnection(ConfigurationManager.ConnectionStrings["ITPCNMSCon"].ToString()); } //To view employee details with generic list public List<Manufactures> ManufactureGetAll(string manufacture = "") { Connection(); List<Manufactures> EmpList = new List<Manufactures>(); SqlCommand com = new SqlCommand("_spManufactureGet", con) { CommandType = CommandType.StoredProcedure }; if (string.IsNullOrEmpty(manufacture)) { com.Parameters.AddWithValue("@Manufacture", DBNull.Value); } else { com.Parameters.AddWithValue("@Manufacture", manufacture); } SqlDataAdapter da = new SqlDataAdapter(com); DataTable dt = new DataTable(); con.Open(); da.Fill(dt); con.Close(); //Bind EmpModel generic list using LINQ EmpList = (from DataRow dr in dt.Rows select new Manufactures() { ManufactureID = Convert.ToInt32(dr["ManufactureId"]), Manufacture = Convert.ToString(dr["Manufacture"]), ManufactureDescription = Convert.ToString(dr["ManufactureDescription"]), IsActive = Convert.ToBoolean(dr["IsActive"]) }).ToList(); return EmpList; } 

4. 存放程序

    SELECT * FROM _Manufacture WHERE Manufacture = ISNULL(@Manufacture,Manufacture) ORDER BY Manufacture 

我的问题是，我想使用sql连接在视图上提供排序和分页。 我怎样才能做到这一点？ 请指教。

谢谢。

Answer 1

 int pageSize = 10;
 int skip = 0;
 int recordsTotal = 0;

其中pagesize是要在网格中显示的记录数，其中skip是选择记录的起点， recordsTotal在网格中的记录总数。

  recordsTotal = EmpList.Count();
  EmpList= EmpList.Skip(skip).Take(pageSize).ToList();

Answer 2

您需要传递页码以及每个请求要获取的记录数和数量。

@PageNumber int
@Records int


Declare @StartingPoint int, @EndingPoint int
Set @StartingPoint = ((@PageNumber -1 ) * @Records)+1
Set @EndingPoint = @PageNumber  * @Records
Select * from (
  Select Dense_Rank() over(order by <PK>) Order,* from <Table>
)TempRecord where [Order]>= @StartingPoint  and [Order]<=@EndingPoint 

所以现在当您调用此存储过程时，请传递PageNumber和Records参数值

当您为PageNumber传递1并为记录传递10时，StartingPoint将为1，EndingPoint将为10，因此您将获得10条记录。对于第2页，StartingPoint将为11，EndingPoint将为20，因此您将获得10条记录。

感谢您的所有答复。 我有自己的答案。 我在下面的教程中创建排序和分页。

非常感谢。
