Ejemplo: consultar metadatos y detectar cambios
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.
Este código de ejemplo se puede encontrar en las siguientes ubicaciones en el paquete de descarga:
SampleCode\CS\Metadata\MetadataQuery\MetadataQuerySample.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 usar clases y métodos en los espacios de nombre Microsoft.Xrm.Sdk.Metadata.Query y Microsoft.Xrm.Sdk.Metadata para consultar los elementos específicos de metadatos y efectuar un seguimiento de los cambios en los metadatos de la organización.
Ejemplo
Esta muestra crea una caché en la memoria de todas las etiquetas de opciones de conjunto de opciones para determinadas entidades. A continuación, se añade una entidad personalizada que contiene atributos de OptionSet y se actualiza la caché de las etiquetas de opciones de conjuntos de opciones. A continuación, se añade una sola opción a uno de los atributos de OptionSet personalizados y se actualiza la caché para agregarla. Finalmente, se elimina la entidad personalizada y la memoria caché de etiquetas de opción del conjunto de opciones se vuelve a actualizar para reflejar este cambio.
El ejemplo mostrará un resultado similar al siguiente cuando se complete.
463 etiquetas de opción para 5 entidades a la memoria caché.
ClientVersionStamp: 296297!10/22/2012 21:41:57
Adición de una entidad personalizada denominada sample_SampleEntityForMetadataQuery con un atributo de conjunto de opciones personalizado denominado : sample_ExampleOptionSet
Se agregaron 8 etiquetas de opción para 1 entidad a la memoria caché.
471 etiquetas de opción almacenadas en la memoria caché
No se ha eliminado ninguna etiqueta de opción.
ClientVersionStamp: 296646!10/22/2012 21:42:06
Adición de una opción adicional a las opciones de atributos de sample_ExampleOptionSet.
Se agregaron 1 etiquetas de opción para 1 entidad a la memoria caché.
472 etiquetas de opción almacenadas en la memoria caché
No se ha eliminado ninguna etiqueta de opción.
ClientVersionStamp: 296649!10/22/2012 21:42:16
Opciones actuales: 472
Eliminación de la entidad personalizada sample_SampleEntityForMetadataQuery
No se agregó ninguna etiqueta de opción a la memoria caché.
9 etiquetas de opción eliminadas
463 etiquetas de opción en total almacenadas actualmente en la memoria caché
ClientVersionStamp: 297079!10/22/2012 21:42:34
