Ejemplo: volcar metadatos de lista desplegable de atributo a un archivo
Publicado: enero de 2017
Se aplica a: Dynamics 365 (online), Dynamics 365 (on-premises), Dynamics CRM 2016, Dynamics CRM Online
Este código de muestra es para Microsoft Dynamics 365 (en línea y local).Descargue el paquete de SDK de Microsoft Dynamics CRM. Se puede encontrar en la siguiente ubicación en el paquete de descarga:
SampleCode\CS\Metadata\Attributes\DumpPicklistInfo.cs
Requisitos
Para obtener más información acerca de los requisitos de ejecución del código de ejemplo proporcionado en este SDK, vea Usar el ejemplo y el código auxiliar.
Muestra
Este ejemplo muestra cómo escribir todos los metadatos de la entidad en un archivo XML. Usa el mensaje de RetrieveAllEntitiesRequest.
El siguiente ejemplo crea un nuevo archivo en \Entities\bin\Debug\AttributePicklistValues.xml. Puede abrir este archivo en Microsoft Office Excel para ver un informe tabular. Esto resulta útil para buscar los valores válidos para cada lista desplegable. Esta información se puede encontrar en el tema "Metadatos del atributo OptionSet de la entidad EntityName" para cada entidad.
