Querying the XML file using LINQ

In this example i tried to find the available balance by passing the account number as parameter to the function through Linq

  
        XDocument doc = XDocument.Load("C:\\Account.xml");
        var result = from ds in doc.Descendants("Account")
                     where ds.Element("IDNumber").Value == account.ToString()
                     select new
                     {
                         Balance = ds.Element("AvailableBalance").Value,
                         AccountID = ds.Element("IDNumber").Value

                     };
        return result.ToArray();

My accounts XML will be
