I am trying to read the xml document using XDocument method . but i am getting an error when xml has

<?xml version="1.0" encoding="utf-16"?>

When i removed encoding manually.It works perfectly.

I am getting error " There is no Unicode byte order mark. Cannot switch to Unicode. "

i tried searching and i landed up here-->

Why does C# XmlDocument.LoadXml(string) fail when an XML header is included?

But could not solve my problem.

My code :

XDocument xdoc = XDocument.Load(path);

Any suggestions ??

thank you.

It looks like the file you are trying to read is not encoded as Unicode. You can replicate the behavior by trying to open a file encoded as ANSI with the encoding in the XML file specified as utf-16.

If you can't ensure that the file is encoded properly, then you can read the file into a stream (letting the StreamReader detect the encoding) and then create the XDocument:

using (StreamReader sr = new StreamReader(path, true)) { XDocument xdoc = XDocument.Load(sr); }

I have my the output of XML being spit into html. The above solution did not work for me. I have a copyright symbol (c) in my text of the xml document and it always gets garbled when the HTML comes to the browser. So I tried to encode (XML encode the HTML encoded string) but it literally comes out as it is in HTML. i.e. &amp;copy; in xml literally comes out as &amp;copy; instead of the expected &copy; so that the browser can display the (c).

I tried , and found another way of doing it !!

XDocument xdoc = XDocument.Parse(System.IO.File.ReadAllLines(path));

Wow! This is new, 4.5 was just released! (2012-08-15 - 5 days ago) :) Way to stay up on your framework Sangram!
From what I can tell the XDocument.Parse() method was new and just introduced to .Net 4.5 framework. That was released on 2012-08-15 which at the time was 5 days ago... It was simply a complement, usually people just say thanks for a complement. :P
Okay. Thanks for that :) but i think existed from 3.5 because i am still using 3.5 :P check msdn.microsoft.com/en-us/library/…
This doesn't compile for me as the Parse method accepts a string and the ReadAllLines method returns a string array! Shouldn't it be ReadAllText?
XDocument.Parse expects a string, so File.ReadAllLines doesn't compile. You have to use File.ReadAllText. At least, that's how it's working for me in VS2017.

This code:

System.IO.File.ReadAllLines(path)

returns an array of strings. The correct code is:

System.IO.File.ReadAllText(path)
