OracleConnection.Open Method ()


Opens a connection to a database with the property settings specified by the ConnectionString.

Namespace:   System.Data.OracleClient
Assembly:  System.Data.OracleClient (in System.Data.OracleClient.dll)

public override void Open()

Exception Condition

The connection is not open.


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.


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.
