Linq To Xml - Create Dictionary From Repetitive XML

I have an XML string like this:

<root>
  <name>Key</name>
  <value>Value</value>
  <name>Key</name>
  <value>Value</value>
  <name>Key</name>
  <value>Value</value>
</root>

How can I produce a C# dictionary that corresponds to this - i.e for each pair of name and value create a dictionary item. (with use of Linq To XML).

I would try something like this ...

XDocument doc = XDocument.parse(... parse you XML here ...);
var nameElements = doc.Descendants("name");
var dictionary = nameElements.ToDictionary(el => el.Value,
                                           el => el.ElementsAfterSelf().First().Value);

This first finds all the name elements, then projects this array to a dictionary. The key selector uses el.Value, which is the value of the name element. The value selector takes the next sibling of the element, which will be your value element.

You can use ToDictionary():

var dict = XElement.Parse(yourMarkup).Elements("name").ToDictionary(
    name => name.Value,
    name => name.ElementsAfterSelf("value").First().Value);
