your problem you're converting string utf-16, though xdocument expecting utf-8.

either use right encoding:

string s = e.result; xmlreader r = xmlreader.create(new memorystream(encoding.utf8.getbytes(s))); xdocument result = xdocument.load(r); 

or more simply, use directly xdocument.parse:

string s = e.result; xdocument result = xdocument.parse(s);
