I got this LinQ statement
var daysList = new List<int>(new int[30]);
var model_pdv = db_pdv.Pdv.GroupBy(x => new { Pdv = x.Clave_PDV, Nombre_Pdv = x.Nombre_Pdv})
.Select(x => new DishVM()
{
Clave_PDV = x.Key.Pdv,
Nombre_Pdv = x.Key.Nombre_Pdv,
Days = daysList,
Data = x
}).ToList();
However i dont know why my "Data" List inside my LinQ gets empty values the first time but then i saves the LinQ as it should
This is my DishVm Class:
public class DishVM
{
public string Clave_PDV { get; set; }
public string Nombre_Pdv { get; set; }
public IEnumerable<Pdv> Data { get; set; }
}
And my Pdv class:
public class Pdv
{
public string Clave_PDV { get; set; }
public string Nombre_Pdv { get; set; }
}
How can i avoid the empty Data List?
The type of x
within your Select
statement is IGrouping, change it to produce a list:
var model_pdv = db_pdv.Pdv.GroupBy(x => new { Pdv = x.Clave_PDV, Nombre_Pdv = x.Nombre_Pdv})
.Select(x => new DishVM()
{
Clave_PDV = x.Key.Pdv,
Nombre_Pdv = x.Key.Nombre_Pdv,
Days = daysList,
Data = x.ToList()
}).ToList();
