Open Method (DbConnectionBase)

In This Topic

Opens a data source connection with the property settings specified by the ConnectionString.

Syntax

Visual Basic
C#

'Declaration
 
Public Overrides Sub Open()

public override void Open()

Remarks

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

Opening an open connection does nothing.

Requirements

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
