I think you should have a look at the classes & interfaces that ADO.NET provides to you:

IDbConnection, ICommand, SqlConnection, SqlCommand, etc…. Have a look in the System.Data namespace.

For instance:

// setup a connection to a sql server SqlConnection conn = new SqlConnection( 'here is the connectionstring' );  SqlCommand cmd = new SqlCommand(conn); cmd.CommandText = 'SELECT * FROM table WHERE Id = @pId'; cmd.Parameters.Add ('@pId', SqlDbType.Int).Value = 1;  using( SqlDataReader dr = cmd.ExecuteReader() ) { }
