Called repeatedly during component design, and at the end of component execution. Components should release any connections that were opened and maintained in AcquireConnections.

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 Not (oledbConnection Is Nothing) AndAlso Not (oledbConnection.State = ConnectionState.Closed) Then 
   oledbConnection.Close 
 End If 
End Sub
