I have a dataset in C# which I can serialise using dataset.WriteXml(filename); but I want the file to contain other data as well (essentially some meta data about the dataset).

I could add another table to the dataset which contained the metadata, but I'd prefer to keep it separate, if at all possible.

Essentially I think I want to create a 'combination of files' file, that looks something like this:

size_of_file1
file1
size_of_file2
file2
... etc

Then, I'd like to load the file into memory, and split the file into separate streams, so that I can feed the dataset into dataset.ReadXml(stream); and the metadata into something else.

Sound possible? Can anyone tell me how I can do it?

Thanks

Tim
