Write to String using the FixedLengthClassBuilder

I have a c# class called "SepaRecord", already defined in a dll which I cannot modify. I have a List at runtime which I need to convert into a fixed length file.

The approach which I have tried is, using the FixedLengthClassBuilder I create a runtime definition of the record, as below:

FixedLengthClassBuilder fileRecordBuilder = new FixedLengthClassBuilder("SepaRecord");
fileRecordBuilder.AddField("RecordCode", 2, typeof(string));
fileRecordBuilder.AddField("CurrencyCode", 3, typeof(string));
fileRecordBuilder.AddField("CreditAmount", 15, typeof(int));
// other fields follow....

RecordCode, CurrencyCode, CreditAmount, etc are fields defined the "SepaRecord" class in the DLL.

I would expect that if I pass the list to the FileHelperEngine, I would get back a delimited string:

List<SepaRecord> lst = this.goGetMyList();
string ret = this.FileHelperEngine.WriteString(lst);

But of course it did not work since the FixedLengthClassBuilder builts and compiles a type/class at runtime and compares it with the class/type of the argument.

Question is: Is there a better approach to do what I am trying to do?

And a suggestion: Why bother with type checks? Just compare on the field level. I think this would make the runtime engine more flexible.

Appreciate any help Chris
