使用视图的实体框架DateTime

Question

I have the following view in my DB

create view myview
as 
select  
      date_reception ,
      location ,
      parameter

      from mytable

in the model i have the following class

 public partial class full
 {

    public Nullable<System.DateTime> date_reception { get; set; }
    public string location { get; set; }
    public string parameter { get; set; }

 }

And i execute the following query in controller

DateTime dt = new DateTime(2015,01,01);
var temp = (from p in db.full
            where (p.date_reception > dt)
            group p by p.parameter into g
            orderby g.Count() descending
            select new StringIntType
            {
                str = g.Key,
                nbr = g.Count()
            }).ToList();

After running the query keeps executing till i get this error message :

System.Data.Entity.Core.EntityCommandExecutionException

Answer 1

public partial class full
 {

    public DateTime? date_reception { get; set; } //it's nullable
    public string location { get; set; }
    public string parameter { get; set; }

 }

it seems that problem is your datetime object.

DateTime dt = new DateTime();
DateTime dt2 = new DateTime();
if (DateTime.TryParse("2015, 01, 01", out dt2))
{
   dt = dt2;
}
