问题 I am trying to read a XML document without expanding the entities, do some manipulations to it, and re-save it with the unexpanded entities as they were initially. When using the XDocument directly, it fails to load, throwing an exception tell me it has unexpanded entities: XDocument doc = XDocument.Load(file); // <--- Exception // ... do some manipulation to doc doc.Save(file2); Exception: Reference to undeclared entity 'entityname'.
