Question

Having this model class

public class Usuario
{
    #region Atributos
    private int _intID = 0;
    private Perfil _Perfil_FK = null;
    private String _strNombre = "";
    private String _strPassword = "";
    #endregion

    #region Propiedades
    public int ID
    {
        get { return _intID; }
        set { _intID = value; }
    }
    public virtual Perfil Perfil_FK
    {
        get { return _Perfil_FK; }
        set { _Perfil_FK = value; }
    }
    public int PerfilID { get; set; }
    public String Nombre
    {
        get { return _strNombre; }
        set { _strNombre = value; }
    }
    public String Password
    {
        get { return _strPassword; }
        set { _strPassword = value; }
    }
    #endregion
}

I’m trying to use this query, the data base table have data, so i can’t see the problem?

 Usuario user = (from U in _db.Usuario
                            where ((U.Nombre == model.UserName) && (U.Password == encripPassword))
                            select U).First();

If you need more info about the data base let me know to update my question

Answer 1

• Does the table actually have a row with that name and password?
• When you run the generated SQL statement in SQL Management Studio, do you get a result?

Suggest checking your two values in UserName and encripPassword for valid values.

Usuario user = _db.Usuario
                  .FirstOrDefault(x=>x.Nombre == model.UserName
                                 &&  x.Password == encripPassword);

string sql = (user as ObjectQuery).ToTraceString(); //the SQL query generated.

if(user==null)
{
  //doesn't exist.
}
