备注

Business Data clients can use two forms of connection management:

1. Explicit connection management

2. Implicit connection management

Explicit connection management is more complex but is useful and performant when sharing connections. For example, if three Business Data web parts want to share a connection to a backend and query it sequentially, implicit connection management would open and close a connection in each case. It is better to explicitly open a connection using LobSystemInstance.OpenConnection(), make the 3 Business Data Catalog object model calls from the 3 Business Data web parts and then close the connection. CloseConnection allows closing an explicitly opened connection.
