Return Object Code as soon as inserted

Question

I need to do an Insert in the Entity Framework and at the same time returns the code of the inserted object, thus preventing new access to the bank.

Answer 1

I understand that you want the return of an object ID, if the ID column is integer and IDENTITY.

Whereas the mapping was done within the norms of the Entity Framework:

[DisplayColumn("Nome")]
public class Fruta
{
    [Key]
    public int FrutaId { get; set; }
    [Required]
    public String Nome { get; set; }
    ...
}

Just enter and read the Object ID:

var fruta = new Fruta { Nome = "Laranja" };
context.Frutas.Add(fruta);
context.SaveChanges();

var idDaFruta = fruta.FrutaId;
