Question

I have a TextReader which has been created by a black-boxed system so I don’t have any information about the source file from which it was created.

I need to pass this TextReader back into the black-boxed system inside an object which I am creating in my application.

However, I need to get some information from the TextReader to assist with the creation of my object.

I understand that you can’t “rewind” a TextReader but is there a way to duplicate it so that I can read and discard a temporary copy without advancing the source TextReader at all?

I have had a look at this SO thread but I’m not sure if that relates to my requirement.

If it does, could someone please elaborate so I can understand?

Thanks in advance.

Well sort of hack, but you can do like this, ReadToEnd the entire text in a string, do what you want, and pass back a new StringReader created with the string you read before. I expect the blackboxed system will work like a charm.
