備註
The IDbConnection interface enables you to implement a Connection class, which represents a unique session with a data source. The IDbConnection interface can be used to build a custom data provider. For more information about Connection classes, see 為資料處理延伸模組實作 Connection 類別.
An application does not create an instance of the IDbConnection interface directly, but creates an instance of a class that implements IDbConnection.
Classes that implement IDbConnection must implement all required members, and typically define additional members to add provider-specific functionality. Because IDbConnection inherits from IExtension, you must also implement the IExtension members as part of your Connection class.
When you implement from the IDbConnection interface, you should also implement the following constructors:
Class |
Description |
|---|---|
PrvConnection() |
Initializes a new instance of the PrvConnection class. |
PrvConnection(string connectionString) |
Initializes a new instance of the PrvConnection class when given a string containing the connection string. |
