How will i read the value inside the second key element ?

I need a result of 1.5

I was trying around, but wasn't successfull yet

XElement doc = XElement.Parse(xml);
//var nodes = doc.DescendantNodes();
//var nodes2 = doc.Nodes().;
//string keyValue =   ((XElement)doc.Descendants().Descendants("dict").ElementAt(1).NodesBeforeSelf().Last()).Value;
int countElements = doc.Descendants().Count();
for (int i = 0; i < countElements; i++)
{
          string test = doc.Element("key").Value;
          //string keyValue = ((XElement)doc.Nodes().ElementAt(i).Last()).Value;
}
//string keyValue = ((XElement)doc.Descendants("dict/Version").DescendantNodes().Last().

Answer 1

Assuming your XML schema is fixed and you don't need to check against erroneous xml:

var result = (doc.Descendants("key")
                 .Single(e => e.Value == "Version")
                 .NextNode as XElement).Value;

Answer 2

try linq to xml

string xml = @"<root>

               <fruit>1</fruit>

                <tree>2</tree>

               </root>";

XDocument dox = XDocument.Parse(xml);

var node = dox.Descendants().Where(n => n.Name == "fruit").FirstOrDefault();

string nodeValue;

if (node != null)

    nodeValue = node.Value;

In your case

doc.Descendants("key").Where(x => x.Name == "version").NodesAfterSelf().OfType<XElement>().First();
