)

Paramètres

• filterCollection
  The FilterCollection object. It must contain the Filters returned by calling the .GetFilters() method on the Finder MethodInstance or by calling .GetFinderFilters on the Entity itself. Each filter returned may have its value set before being used here to return a filtered set of Instances.

• lobSystemInstance
  The LobSystemInstance object.

Valeur de retour

An entity instance collection enumerator.

Exemple

This example shows how to execute a Finder method on the Product entity in the AdventureWorks2000 sample.

Prerequisites

• Ensure a Shared Service Provider is already created.

• Replace the constant value EnterYourSSPNameHere in the code with the name of your Shared Resource Provider.

• Make sure the LobSystem object and entity names referenced in the example exist in the Business Data Catalog. Use valid names.
