Answer 1

string xmlPath = Server.MapPath("~/xmlTest.xml");
            XDocument xd = XDocument.Load(xmlPath);
            var temp = (from x in xd.Descendants("Data")
                        select new
                        {
                            CorpOrderID = x.Attribute("CorpOrderID").Value
                        }).ToList();

            foreach (var item in temp)
            {
                litMsg.Text += item.CorpOrderID + "<br/>";
            }

Answer 2

using System.Xml.Linq;
XElement xml = XElement.Load(@"D:\Test\user.xml");
var query = xml.Descendants("Data");
foreach (var item in query)
{
    Console.WriteLine(item.Attribute("CorpOrderID").Value);
}
