OracleConnection::Open Method ()

Other Versions

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)

Syntax

C++

public:
virtual void Open() override

Implements

IDbConnection::Open()

Exceptions

Exception	Condition
InvalidOperationException	The connection is not open.
OracleException	Cannot change the database.

Remarks

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

Note
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.
