ApplicationRegistry 类 (Microsoft.Office.Server.ApplicationRegistry.MetadataModel)

Provides access to all the line-of-business (LOB) systems and LOB system instances registered in the Business Data Catalog. This is the top-level object in the Business Data Catalog's object model. It enables you to read all the metadata objects including LOB system, entities, and methods.

public sealed class ApplicationRegistry

备注

The Business Data Catalog is implemented as an Office SharePoint Server 2007 core service and is shared across a Shared Resource Provider. Therefore, before you can use the ApplicationRegistry object, you must specify the Shared Resource Provider associated with the Business Data Catalog.

示例

The following code example shows how to display the names of the systems that are registered in the Business Data Catalog. Specifying the Shared Services Provider (SSP) is one of the first step sin a console application to work with the Business Data Catalog.

After you specify the Shared Services Provider, you can use the ApplicationRegistry object to get the LobSystemInstance objects that are registered with the Business Data Catalog, as shown in the following example.

Prerequisites

• Ensure a Shared Services Provider is already created.

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