Date de publication : janvier 2017
S’applique à : Dynamics 365 (online), Dynamics 365 (on-premises), Dynamics CRM 2016, Dynamics CRM Online
Cet exemple de code est pour Microsoft Dynamics 365 (Online et local).Téléchargez le package Kit de développement logiciel (SDK) de Microsoft Dynamics CRM. Il se trouve à l'emplacement suivant dans le package de téléchargement :
SampleCode\CS\Metadata\Attributes\DumpAttributeInfo.cs
Configuration requise

Démontre
Cet exemple montre comment écrire toutes les métadonnées d’attribut dans un fichier XML. Il utilise le message RetrieveAllEntitiesRequest.
L’exemple suivant crée un fichier dans \Entities\bin\Debug\AllAttributeDesc.xml. Vous pouvez ouvrir ce fichier dans Microsoft Office Excel pour afficher un rapport sous forme de tableau. Vous pouvez facilement rechercher des informations telles que les attributs pouvant être définis dans une opération de création, de récupération ou de mise à jour. Ces informations se trouvent également dans la rubrique « Métadonnées de l’attribut de l’entité EntityName » pour chaque entité.
