linq to XML doc.save is failing, c#

I have a c# program that creates an xml document using linq to xml:

XDocment doc = new XDocument();

there are over 600 lines of logic building this xml file, culminating in:

string fName = this._writepath + "file856" + curDateTime + ".xml";
doc.Save(fName);


at doc.Save I am getting an error:  This operation would create an incorrectly strucutred document.  

Unfortunately, this error doesn't happen in my development environment, only in the delivery environment (the executable on the client's machine).

Is there anything I can do to get the executable to show me the structure of the xml so that I can see where it's malformed?  In other words, since doc.Save fails, is there some way to throw it into a viewer or a NotePad or something else that would allow me to look at it?

what encoding are you using, be very wary of UT8 or other non standard formats

I'm using utf-8.  How does that play into this?  The .ToString() method returned the same error.

typo - should have been utf-8, utf-8 generally should be ok then - you probably constructing a document that is not well formed...

Correct -- I agree that it's not well-formed.  I am looking for a way to display it so that I can spot the error.  So far, I have not been able to get any application of .ToString() to do that for me.

Fernando SotoRetiredCommented:
The problem is that when you create the document it goes through a XML validation process and if it fails it will not get loaded and therefore there will nothing to print. To find the issue you will need to go through the code that creates it and find where it is being malformed.
