My own answer

XDocument Xdoc = new XDocument(new XElement("Users"));
        if (System.IO.File.Exists("D:\\Users.xml"))
            Xdoc = XDocument.Load("D:\\Users.xml");
        else
        {
            Xdoc = new XDocument();
            XElement xmlstart = new XElement("Users");
            Xdoc.Add(xmlstart);
        }
        XElement xml = /*new XElement("Users",*/
                       new XElement("User",
          new XElement("UserId", txtUserId.Text),
          new XElement("Password", txtPwd.Text));

        if (Xdoc.Descendants().Count() > 0)
            Xdoc.Descendants().First().Add(xml);
        else
        {
            Xdoc.Add(xml);
        }

        Xdoc.Element("Users").Save("D:\\Users.xml");

This is giving me xml like

<?xml version="1.0" encoding="utf-8"?>
<Users>
  <User>
  <UserId>Sunny</UserId>
  <Password>Sunny</Password>
 </User>
 <User>
   <UserId>Sunny</UserId>
   <Password>Sunny</Password>
 </User>
 <User>
   <UserId>Sunny</UserId>
   <Password>Sunny</Password>
 </User>
</Users>

Then use XElement instead of XAttribute.

 new XElement("User",
              new XElement("UserId", txtUserId.Text),
              new XElement("Password", txtPwd.Text));

And to add multiple users, given that you have userList:

 new XElement("Users",
        userList.Select(u=>
             new XElement("User",      
                 new XElement("UserId", u.UserId),
                 new XElement("Password", u.Password)));

Answer 3

If you want the values to appear as elements then you should use XElement instead of XAttribute...

E.g.

XElement xml = /*new XElement("Users",*/
                   new XElement("User",
                   new XElement("UserId", "sunny"),
                   new XElement("Password", "pwd")
                   );

To add these elements under the root use:

Xdoc.Element("Users").Add(xml);

Answer 4

It just changed from XAttribute to XElement. Because attributes would be added inside the element like . Elements play a different role which form a tree XML structure.

The Root element is now become Users as per your requirement.

XElement xml = new XElement("Users",   
                       new XElement("User",
                       new XElement("UserId", "sunny"),
                       new XElement("Password", "pwd")
                       ));

If you want repeatedly add the child element use the below code block either individual or in loop.

xml.Add(
new XElement("User", new XElement("UserId", "sunny"), new XElement("Password", "pwd") ) );

Refer your complete sample

XDocument Xdoc = new XDocument(new XElement("Users"));
        if (System.IO.File.Exists("D:\\Users.xml"))
            Xdoc = XDocument.Load("D:\\Users.xml");
        else
            Xdoc = new XDocument();

       XElement xml = /*new XElement("Users",*/
                       new XElement("User",
                       new XElement("UserId", "sunny"),
                       new XElement("Password", "pwd")
                       );

        if (Xdoc.Descendants().Count() > 0)
            Xdoc.Descendants().First().Add(xml);
        else
        {
            Xdoc.Add(xml);
        }

        Xdoc.Save("D:\\Users.xml");

Give a try for this,

    var users= new XElement("Users");

    var userXml= new XElement("User",
                   new XElement("UserId", txtUserId.Text),
                   new XElement("Password", txtPwd.Text)
                   );

    users.Add(userXml);
