Bonjour,
j'ai un
problème pour ajouter des éléments dans une collection : tousles
éléments sont égaux. Grâce au débogueur (pas-à-pas) j'ai constatéque
lors de l'ajout d'un élément tous les éléments étaient modifiés
parcelui qui est ajouté. Donc tous les éléments de ma liste sont égaux
audernier élément ajouté. Comme si les éléments de la liste
faisaientréférence à la même case mémoire ;-)
while(reader.read())
{
int id
=(int)Convert.ToInt32(reader["id_vitrine"]);
DateTime dbt;
dbt = new
DateTime(dt.Year, dt.Month,dt.Day, dt.Hour, dt.Minute, dt.Second);
DateTime fin;
fin =
(DateTime)reader["date_fin"];
DateTime locked;
locked =
(DateTime)reader["date_locked"];
int actif;
actif
=Convert.ToInt32(reader["actif"].ToString());
int css;
css =
Convert.ToInt32(reader["id_css"]);
vc.Add(new Vitrine(id, dbt, fin, locked, actif, css));
}
public int Add( Vitrine value )
{
//value = newVitrine(value.Id,
value.date_dbt, value.date_fin, value.date_locked,value.actif,
value.css);
//return (List.Add( value ));
return(List.Add(new
Vitrine(value.Id, value.date_dbt, value.date_fin,value.date_locked,
value.actif, value.css)));
}
Merci
d'avoir pris le temps de me lire. Si vous avez une solution ouune idée,
je vous en remercie par avance de me laisser un petit message.
