I am to provide a proxy or adapter or facade - I'm unsure what pattern to use - in providing import and export routines from one file format to another.

 

If you have an opinion on what design pattern best fits this, I would appreciate your feedback.

 

Thanks.

Why use any particular pattern? Wouldn't an interface do?

 

interface IFileFormat {

 

String Name FileFormatName { get; }

 

InternalFileFormat Import(Stream stream);

 

void Export(InternalFileFormat internalRepresentation, Stream stream);

 

}

I would have through strategy would be the best bet, with a different concrete strategy for each format.
