Linq to XML -Dictionary转换

Question

如何将以下节点存储到Dictionary中,其中int是使用LINQ的自动生成的Key和字符串(节点的值)？

Elements:

XElement instructors =
         XElement.Parse(
                          @"<instructors>
                               <instructor>Daniel</instructor>
                               <instructor>Joel</instructor>
                               <instructor>Eric</instructor>
                               <instructor>Scott</instructor>
                               <instructor>Joehan</instructor> 
                         </instructors>"
        );

partially attempted code is given below :

var  qry = from instr in instructors.Elements("instructor")
where((p,index)=> **incomplete**).select..**incomplete**; 

如何将我的选择变成Dictionary<int,String>？(键应从1开始;在Linq标记从零开始).

怎么样:

var dictionary = instructors.Elements("instructor")
                            .Select((element, index) => new { element, index })
                            .ToDictionary(x => x.index + 1,
                                          x => x.element.Value);
