UWP - XDocument Equivalent Of XMLNodeList

If I had an XMLDocument and wanted to for example count the number of results of a Node I would use something like

        //XmlNodeList CountResultsReturned = XMLSearch.SelectNodes("root/item");
        //if (CountResultsReturned.Count > 1)
        //{}

I was wondering how I would achive something like this using XDocument instead.

There is no specific class in LINQ to XML which is equivalent to XmlNodeList, because LINQ to XML simply works with sequence of nodes IEnumerable<XNode> or sequence of elements IEnumerable<XElement>. When you select some nodes it just yields matching nodes one by one. You can store sequence to list or other collection, if you want to. E.g

var items = xdoc.Root.Elements("item").ToList();

For your code just select elements and use LINQ Any() method to check if any elements exist:

xdoc.Root.Elements("item").Any()
// items.Any()

You can also use Count() to get number of elements. Of course XPath also available

xdoc.XPathSelectElements("root/item").Count()
// items.Count
