    Object^ connection
)

abstract ReleaseConnection : 
        connection:Object -> unit

public function ReleaseConnection(
    connection : Object
)

参数

• connection
  类型：System. . :: . .Object

注释

This method is called repeatedly during component design by the runtime engine and at the end of component execution. The components then release any connections that were opened and maintained in AcquireConnection. This method is called only when OfflineMode is false.

示例

private System.Data.OleDb.OleDbConnection oledbConnection;
public override void ReleaseConnections()
{
    if (oledbConnection != null && oledbConnection.State != ConnectionState.Closed )
        oledbConnection.Close();
}

Private oledbConnection As System.Data.OleDb.OleDbConnection
Public Overrides  Sub ReleaseConnections()
    If oledbConnection <> Nothing And oledbConnection.State <> ConnectionState.Closed Then
        oledbConnection.Close()
    End If
End Sub
