Свойства

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

Замечания

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 Реализация класса Connection для модуля обработки данных.

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.
