$ dotnet add package System.Data.OleDbThis package implements a data provider for OLE DB data sources.
Allows access to legacy OLE DB data sources.
This is a basic example of retrieving the results of a query using an OleDbDataReader. For examples of using an OleDbDataAdapter, and of updating an OLE DB data source, please see the documentation.
using System.Data.OleDb;
string connectionString = ""; // Fill in
string queryString = "SELECT OrderID, CustomerID FROM Orders";
using OleDbConnection connection = new OleDbConnection(connectionString);
using OleDbCommand command = new OleDbCommand(queryString, connection);
connection.Open();
using OleDbDataReader reader = command.ExecuteReader();
while (reader.Read())
{
Console.WriteLine(reader.GetInt32(0) + ", " + reader.GetString(1));
}
DataSet and update the OLE DB data source.System.Data.Odbc is a similar package for accessing ODBC data sources.
