Assembly: System.Data (in System.Data.dll)
The OleDbConnection draws an open connection from the connection pool if one is available. Otherwise, it establishes a new connection to the data source. You can open more than one DataReader on a single OleDbConnection. If the OLEDB provider you use does not support more than one active DataReader on a single connection, the OLEDB provider implicitly opens an additional connection for each.
