Je veux supprimer tous les affichages de ma région dans Composite. J'utilise Silverlight 4.0.Comment supprimer tous les affichages dans la région dans CompositeWPF/Silverlight
Et malheureusement, ce code se bloque avec OutOfRangeException à l'intérieur de Composite.
List<object> views = new List<object>(_regionManager.Regions["NavigationRegion"].Views);
foreach (object view in views)
{
_regionManager.Regions["NavigationRegion"].Remove(view);
}
Ceci est mon callstack:

Qu'est-ce que j'ai fait?
P.S. Dans ma région j'ai 3 vues. Ainsi, des accidents composites sur l'enlèvement de la troisième.
En espérant vous aider :). Je vous remercie. UPD: J'ai téléchargé les symboles de débogage et j'ai trouvé que le problème se situait uniquement dans le contrôle d'Accordion en tant que région. Ce est pleine pile d'appel:

pourquoi ??? c'est tout le but de foreach - iterating IEnumerables ... – barrypicker
