How to get first object out from List<Object> using Linq

Question

I have below code in c# 4.0.

//Dictionary object with Key as string and Value as List of Component type object
Dictionary>         


        

Answer 1

I would to it like this:

//Dictionary object with Key as string and Value as List of Component type object
Dictionary> dic = new Dictionary>();

//from each element of the dictionary select first component if any
IEnumerable components = dic.Where(kvp => kvp.Value.Any()).Select(kvp => (kvp.Value.First() as Component).ComponentValue("Dep"));

but only if it is sure that list contains only objects of Component class or children
