Deserialize XML To Object using Dynamic

Is it possible Deserialize unknown XML to object like below?

var xml = @"<Students><Student><Name>Arul</Name><Mark>90</Mark></Student></Students>";

var serializer = new XmlSerializer(typeof(DynamicObject));

dynamic students = serializer.Deserialize(new XmlTextReader(new StringReader(xml)));

Answer

You may want to try this.

string xml = @"<Students>
                <Student ID=""100"">
                    <Name>Arul</Name>
                    <Mark>90</Mark>
                </Student>
                <Student>
                    <Name>Arul2</Name>
                    <Mark>80</Mark>
                </Student>
            </Students>";

dynamic students = DynamicXml.Parse(xml);

var id = students.Student[0].ID;
var name1 = students.Student[1].Name;

foreach(var std in students.Student)
{
    Console.WriteLine(std.Mark);
}

public class DynamicXml : DynamicObject
{
    XElement _root;
    private DynamicXml(XElement root)
    {
        _root = root;
    }

    public static DynamicXml Parse(string xmlString)
    {
        return new DynamicXml(XDocument.Parse(xmlString).Root);
    }

    public static DynamicXml Load(string filename)
    {
        return new DynamicXml(XDocument.Load(filename).Root);
    }

    public override bool TryGetMember(GetMemberBinder binder, out object result)
    {
        result = null;

        var att = _root.Attribute(binder.Name);
        if (att != null)
        {
            result = att.Value;
            return true;
        }

        var nodes = _root.Elements(binder.Name);
        if (nodes.Count() > 1)
        {
            result = nodes.Select(n => n.HasElements ? (object)new DynamicXml(n) : n.Value).ToList();
            return true;
        }

        var node = _root.Element(binder.Name);
        if (node != null)
        {
            result = node.HasElements ? (object)new DynamicXml(node) : node.Value;
            return true;
        }

        return true;
    }
}
