Here i want to get Element name(Tag Name) such as Contacts,*Node*,ID,*Name* using linq to xml concept.What should i do for that.

Answer 1

Try this:

var xml = @"<Contacts>
                    <Node>
                        <ID>123</ID>
                        <Name>ABC</Name>
                    </Node>
                    <Node>
                        <ID>124</ID>
                        <Name>DEF</Name>
                    </Node>
            </Contacts>";
var xdoc = XDocument.Parse(xml);
var namelist = xdoc.Descendants()
                    .Select(i => i.Name.ToString())
                    .Distinct()
                    .ToList();

You will get:

{"Contacts","Node","ID","Name"}

If you want to get the name list of first node

var nodes = xdoc.Descendants(XName.Get("Node"));
var firstNode = nodes.First();
var namelist = firstNode.Descendants()
                    .Select(i => i.Name.ToString())
                    .Distinct()
                    .ToList();
