i tried this code. but got error,

var files = Directory.GetFiles(txtpath.Text);

foreach (var f in files)

{

//doc = XDocument.Load(f);
XmlDocument xmldoc = new XmlDocument();
xmldoc.LoadXml(f.Substring(f.IndexOf(Environment.NewLine))); // Error In this line.
var node = xmldoc.SelectSingleNode("//DOCTYPE");
if (node != null)
{

@Ashish,

Thanks For Your Replay. I did that by using doc.DocumentType.

You are getting error because DocType is not an ordinary XML node it is Document Type Declaration, all the operations to this should use XmlDocumentType class
