c# - X文档文件名

Question

有没有办法从 XDocument 对象本身检索 XDocument 保存的路径(文件名)？

我的意思是在我已经保存 XDocument 对象之后获取保存的路径。像这样:

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

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

如果加载 XDocument从文件中，BaseUri属性将包含文件名。如 MSDN 中所述:

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.

但是，保存文档时不会设置，仅在加载操作期间设置。因此，如果您需要知道保存路径，则需要在保存时独立于 XDocument 实例进行存储。
