XDocument.Load假设什么是默认编码？

Question

If I use XDocument.Load to parse an XML file...

var x = XDocument.Load("somefile.xml");

...which does not have a <?xml version="1.0" encoding="..."?> header...

<MyRootElement>
   ...
</MyRootElement>

...what is the default encoding assumed by XDocument.Load ? ANSI (ie the system default legacy locale)? UTF-8? Something else?

I have checked the documentation , but it's not documented there. I have also looked at the reference source , but gave up after getting too deep into the XmlReader source.

Answer 1

Internally, it calls XmlReader.Create(string, XmlReaderSettings) . This gives it the same default as that method call. According to the link from Jeroen's comment , the encoding for stream input is auto-detected from the BOM (the default being ASCII if there is no BOM).

However, as per this answer , the default encoding can be overridden by passing in a TextWriter (such as a StreamWriter ):

StreamReader reader = new StreamReader("somefile.xml", Encoding.GetEncoding(1252));
var x = XDocument.Load(reader);
