I can't seem to parse my xml string to a custom object. Here is my code:
private Account parseXmlToAccount (String xml)
{
XDocument doc = XDocument.Parse(xml);
Console.Out.WriteLine("a" + xml);
List<Account> result =
(
from x in doc.Root.Elements("user")
select new Account()
{
Session = (string) x.Element("session").Value,
User = (string) x.Element("user").Value
}).ToList();
Console.Out.WriteLine("b");
return result.First();
And Account.cs:
class Account
{
public string Session { get; set; }
public string User { get; set; }
public override string ToString()
{
return Session + " " + User;
}
}
and my xml string:
<user>
<session>7981239761293767891</session>
<user>873948797862364</user>
</user>
and my error message:

Your root is the user
element, so change:
from x in doc.Root.Elements("user")
to
from x in doc.Elements("user")
List<Account> result = (from o in doc.Elements()
select new Account{
User = o.Element("user").Value,
Session = o.Element("session").Value
}).ToList();
