Dictionary to XML using LINQ

[maylortaylor]

So I have a function that takes in a Dictionary and returns a XML document with the information. It uses LINQ which I suck at and would like some help reformat the information.

So far the information comes out like this:

<UserClassDictionary>
   <adolan>
      <ControlNumber>791301</ControlNumber>
   </adolan>
   <afeazell>
      <ControlNumber>790253</ControlNumber>
   </afeazell>
   <asnyder>
      <ControlNumber>790210</ControlNumber>
      <ControlNumber>790308</ControlNumber>
</UserClassDictionary>

However, I wish to have the format look like this.

<user name="adolan">
<controlNumbers>
<number>123</number>
<number>546</number>
</controlN​umbers>
</user>

Here is the function thus far.

 static void DictionaryToXML(Dictionary<string,User> UserClassDict)
        {
            string xmldoc = "UserClassDictionary.xml";
            Console.WriteLine("Moving User Dictionary data to XML (" + xmldoc + ")...");

            XElement el = new XElement("UserClassDictionary",
       UserClassDict.Select(kv => new XElement(kv.Key,
                    kv.Value.ControlNumber.Select(num => new XElement("ControlNumber", num)))));

            var xml = el.ToString();
            File.WriteAllText(xmldoc, xml);
        }
