Le type IDbConnectionExtension expose les membres suivants.

Propriétés

  Nom Description
Propriété publique ConnectionString Gets or sets the string used to open a database. (hérité de IDbConnection.)
Propriété publique ConnectionTimeout Gets the time to wait, while trying to establish a connection, before terminating the attempt and generating an error. (hérité de IDbConnection.)
Propriété publique 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.
Propriété publique IntegratedSecurity Indicates whether the connection should use integrated security rather than supply a username and password.
Propriété publique LocalizedName Gets the localized name of the extension to be displayed in a user interface. (hérité de IExtension.)
Propriété publique Password Gets or sets the password to use when connecting to the database. Overrides any password specified in the connection string.
Propriété publique UserName Gets or sets the username to use when connecting to the database. Overrides any username specified in the connection string.

Notes

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 Implémentation d'une classe Connection pour une extension pour le traitement des données.

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.
