Namespace: System.Data.OracleClient

public override void Open ()
public void Open ()

Exception typeCondition

InvalidOperationException

The connection is not open.

OracleException

Cannot change the database.

The OracleConnection draws an open connection from the connection pool if one is available. Otherwise, it establishes a new connection to the database.

NoteNote

If the OracleConnection goes out of scope, the connection it represents does not close automatically. Therefore, you must explicitly close the connection by calling Close.
