{
   if (Char.IsLetter(record[0]))
      return RecordAction.Master;
    else
      return RecordAction.Detail;
}
Finally you must to instantiate a MasterDetailEngine and Read/Write files:
Copy
MaterDetailEngine engine = new MaterDetailEngine(typeof(Customers), typeof(Orders), new MasterDetailSelector(ExampleSelector));

// to Read use:
MasterDetail[] res = engine.ReadFile("TestIn.txt");

// to Write use:
engine.WriteFile("TestOut.txt", res);
