Exceptions

Remarks
The OdbcConnection draws an open connection from the connection pool if one is available. Otherwise, it establishes a new connection to the data source.
Note
If the OdbcConnection goes out of scope, the connection it represents does not close automatically. Therefore, you must explicitly close the connection by calling Close, Dispose, or by placing the connection within a Using statement.
