Der IDbConnectionExtension-Typ macht folgende Elemente verfügbar.

Eigenschaften

	Name	Beschreibung
	ConnectionString	Gets or sets the string used to open a database. (Geerbt von IDbConnection.)
	ConnectionTimeout	Gets the time to wait, while trying to establish a connection, before terminating the attempt and generating an error. (Geerbt von IDbConnection.)
	Impersonate	Sets the username of the user that is impersonated while queries are executed. This property is ignored by the report server if impersonation is not supported by the data provider.
	IntegratedSecurity	Indicates whether the connection should use integrated security rather than supply a username and password.
	LocalizedName	Gets the localized name of the extension to be displayed in a user interface. (Geerbt von IExtension.)
	Password	Gets or sets the password to use when connecting to the database. Overrides any password specified in the connection string.
	UserName	Gets or sets the username to use when connecting to the database. Overrides any username specified in the connection string.

Methoden

	Name	Beschreibung
	BeginTransaction	Begins a database transaction. (Geerbt von IDbConnection.)
	Close	Closes the connection to the database. (Geerbt von IDbConnection.)
	CreateCommand	Creates and returns a Command object associated with the connection. (Geerbt von IDbConnection.)
	Dispose	(Geerbt von IDisposable.)
	Open	Initializes a database connection with the settings specified by the ConnectionString property of the provider-specific Connection object. (Geerbt von IDbConnection.)
	SetConfiguration	Used to pass custom configuration data to an extension. (Geerbt von IExtension.)

Hinweise

The IDbConnectionExtension interface enables you to implement an extension of the IDbConnection interface, which adds additional functionality for authenticating a connection to a data source. The IDbConnectionExtension interface can be used to build a custom data processing extension. For more information about Connection classes, see Implementieren einer Connection-Klasse für Datenverarbeitungserweiterungen.

An application does not create an instance of the IDbConnectionExtension interface directly, but creates an instance of a class that implements IDbConnectionExtension.

Classes that implement IDbConnectionExtension must also implement all required members, and typically define additional members to add provider-specific functionality. Because IDbConnectionExtension inherits from IDbConnection, you must also implement all of the IDbConnection members as part of your Connection class including those members from IExtension.
