c# - XElement XML ToString malformed [ ] -

so m parsing xml. create xelement , run tostring() method. @ results , wrong.

<root>[elementname, elementvalue ]</root> 

when should like

<root>   <data name="name">     <value>value</value>   </data> </root> 

this really weird. ive used xml plenty of times , have never run this. have looked on web , cant find anything. when step through xdocument creation process tostring() each element correct. going on ? how can troubleshoot ?

here code

    string writexml(dictionary<string, string> dic)     {         var root = new xelement("root");          foreach (var pair in dic)         {             var element = new xelement("data", pair.value);             element.add(new xattribute("name", pair.key));             root.add(pair);         }          var doc = new xdocument(new xdeclaration("1.0", "utf-8", null), root);          var s = doc.tostring();         console.writeline(s);          return doc.tostring();     }
