XDocument File Name

Question

Is there a way to retrieve XDocument saved path (file name) from the XDocument object itself?

I mean to get the saved path after I already saved the XDocument object. Something like this:

XDocument xDoc = new XDocument();
xDoc.Save(@"C:\Temp\MyXmlDoc.xml");

string str = xDoc.SavedPath() // <== something like this

If you load the XDocument from a file, the BaseUri property will contain the file name. As stated in MSDN:

Sometimes the XmlReader has the base URI, and sometimes it does not. For instance, when loading from a file, the XmlReader knows the base URI, but when reading from an XmlReader that was created because of calling the Parse method, there is no possibility of the XmlReader reporting a base URI; the XML was in a string.

However, this is not set when saving the document, only during load operations. Therefore, if you need to know the save path, you will need to store that independently of the XDocument instance when saving.
