The EDB .NET Connector is a .NET data provider that allows a client application to connect to a database stored on an EDB Postgres Advanced Server host. The .NET Connector accesses the data directly, allowing the client application optimal performance, a broad spectrum of functionality, and access to EDB Postgres Advanced Server features.

The .NET Connector supports the following frameworks:

  • .NET 5.0
  • .NET Core 3.1
  • .NET Standard 2.0 and 2.1

The .NET class hierarchy

The .NET class hierarchy contains classes that you can use to create objects that control a connection to the EDB Postgres Advanced Server database and manipulate the data stored on the server. The following are just a few of the most commonly used object classes.

EDBConnection

The EDBConnection class represents a connection to EDB Postgres Advanced Server. An EDBConnection object contains a ConnectionString that instructs the .NET client how to connect to an EDB Postgres Advanced Server database.

EDBCommand

An EDBCommand object contains an SQL command that the client executes against EDB Postgres Advanced Server. Before you can execute an EDBCommand object, you must link it to an EDBConnection object.

EDBDataReader

An EDBDataReader object provides a way to read an EDB Postgres Advanced Server result set. You can use an EDBDataReader object to step through one row at a time, forward only.

EDBDataAdapter

An EDBDataAdapter object links a result set to the EDB Postgres Advanced Server database. You can modify values and use the EDBDataAdapter class to update the data stored in an EDB Postgres Advanced Server database.
