    // First declare the record class
        
    [Delimitedrecord("|")]
    public class SampleType
    {
        public string Field1;
        public int    Field2;
    }


    public void ReadExample()
    {
        SampleType record;    

        FileHelperAsyncEngine engine = new FileHelperAsyncEngine(typeof(SampleType));

        engine.BeginReadFile("source.txt");
        
        while( engine.ReadNext() != null )
        {
           record = (SampleType) engine.LastRecord;
           
           // put your code here !!!!
           Console.WriteLine("Data " + record.Field1 + " , " + record.Field2.ToString());
        
        }
        
        engine.Close();
    }
