    Inherits Dictionary(Of String, LobSystemInstance)
用法
Dim instance As NamedLobSystemInstanceDictionary

[SerializableAttribute] 
[DefaultMemberAttribute("Item")]

public class NamedLobSystemInstanceDictionary : Dictionary<string,LobSystemInstance>

示例

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

After you specify the Shared Service Provider, you can use the ApplicationRegistry object to get the LobSystemInstance objects 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.
