使用实体框架在CSHTML中绑定动态字段

Question

I have 2 fields in Table . And as per Stored Procedure's query, it gives 4 fields. In that, 2 fields are from Table and other 2 dynamic fields which I can't mapped in Entity Framework directly. So how can I bind that 2 fields in CSHTML .

Following is the code I have tried.

Stored Procedure's Query

SELECT                          
    ROW_NUMBER() Over (Order By Table.Id) SrNo
    ,Id
    ,Name
    ,'10000' Salary
FROM Table

Controller

MyModel model = new MyModel();
SqlParameter param1 = new SqlParameter("@Parameter",1);
model.lstdata = app.Database.SqlQuery<EntityName>("exec ProcedureName @Parameter", param1).ToList();
return View(model);

Model Class

public class Model
{
    public int Id { get; set; }        
    public string Name { get; set; }
    public List<EntityName> lstData { get; set; }
    public Model()
    {
        lstData = new List<EntityName>();
    }
}

CSHTML

@foreach (var item in Model.lstdata)
{
    <tr>     
        <td>
            @Html.DisplayFor(modelItem => item.SrNo)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.Id)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.Name)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.Salary)
        </td>
    </tr>
}

EntityName

namespace Data
{
    [Table("Table")]
    public class EntityName
    {
        [Key]
        public long Id { get; set; }
        public string name { get; set; }

        [NotMapped]
        public int SrNo { get; set; }
    }
}

Please suggest me a best option to come out from this query.

Answer 1

Try below code. Try adding [NotMapped] attribute on the property you don't want to map.

public class EntityName
{
    // ...

    [NotMapped]
    public int SrNo { get; set; }
    [NotMapped]
    public int Salary{ get; set; }

    // ...
}

Answer 2

要绑定视图中的值，我建议创建单独的ViewModelEntity，并且对于数据库操作，请使用Pure POCO类，该类具有与表中相同的字段。
