System.Data.OleDb Namespace

The System.Data.OleDb namespace is the.NET Framework Data Provider for OLE DB.

The.NET Framework Data Provider for OLE DB describes a collection of classes used to access an OLE DB data source in the managed space. Using the OleDbDataAdapter, you can fill a memory-resident DataSet that you can use to query and update the data source.

For information about how to use this namespace, see the OleDbDataAdapter, OleDbDataReader, OleDbCommand, and OleDbConnection classes.
