I'm using the C# FileHelpers library to efficiently parse large delimited files into validation objects.

However, I'd like to be able to map a single input file column to more than one output class property, but can't find an obvious way to achieve this. I've looked at ITransformable, but I don't want to map to yet another object to cut down on memory during the operation, and I've looked at the DynamicFieldBuilder/DynamicClassBuilder objects, but these seem to only allow me to describe what's in the input file, not what should be in the output instance.

I am trying to avoid having to load the file twice or do some kind of object-to-object mapping after the fact.

Input File Example:

```
ColumnA|ColumnB
Foo|Baz

```

Output Class Example:

```
public class FooBar
{
    public string ColumnA_One;
    public string ColumnA_Two;
    public string ColumnB_One;
    public string ColumnB_Two;
}

```
