To query access database you should use System.Data.OleDb namespace
and create connection
OleDbConnection connection = new OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0 ;" +
" User Id=; Password=; Data Source="mdb file name")

Create command
OleDbCommand command = connection.CreateCommand()
command.CommandText = ""

Create DataReader
OleDbDataReader reader = command.ExecuteReader();

cheers.
