In above XML file using Linq i just want to extract OrderNumber and UniqueNumber OrderNumber="1" 11111111111111111111111111111

Any ideas, suggestions to extract these details?

I can select elements from above xml file but UniqueNumber is not associated with OrderNumber

I am looking for something below (ignore lines where UniqueNumber is not present) OrderNumber - assosicated UniqueNumber

Update In "requiredElements" i am expecting two coulmns OrderNumber and UniqueNumber and holding associated values with each other as 1 and 11111 and so one

 #region FileOpen with UTF8 Encoding

 TextReader sr = new StreamReader(cFileName, Encoding.UTF8);
 XDocument reportfile = XDocument.Load(sr, LoadOptions.SetBaseUri);
 XElement xd = XElement.Parse(reportfile.ToString());
 sr.Close();


 #endregion

 XNamespace ns = xd.Attribute("xmlns").Value;

 var requiredElements = (from resultquery in reportfile.Descendants()
                          select new
                          {
                             OrderNumber = resultquery.Attribute("OrderNumber"),
                             UniqueNumber= (string)resultquery.Element(AddNameSpace(ns, "UniqueNumber")),
                          }
                      );

It's not really clear what's failing for you... what do you mean by "UniqueNumber is not associated with OrderNumber"? — Jon Skeet

Here is some sample:

    XDocument doc = XDocument.Load(@"file.xml");
    XNamespace df = doc.Root.Name.Namespace;
    var results = from request in doc.Descendants(df + "Request")
                  where request.Elements(df + "UniqueData").Elements(df + "UniqueNumber").Any()
                  select new
                  {
                      ordNumber = (int)request.Attribute("OrderNumber"),
                      uniqueNumber = (decimal)request.Element(df + "UniqueData").Element(df + "UniqueNumber")
                  };
    foreach (var result in results)
    {
        Console.WriteLine("{0}-{1}", result.ordNumber, result.uniqueNumber);
    }
