c# - Is there a better LINQ Query to do this? -

lets have flat list of objects, each of has person's name, , single role they're in, so:

        var people = new[] {              new personrole(){ name = "adam", role = "r1" },             new personrole(){ name = "adam", role = "r2" },             new personrole(){ name = "adam", role = "r3" },             new personrole(){ name = "bob", role = "r1" },         }; 

now, there direct way dictionary<string, list<string>> based on name , role (obviously). did in 2 steps, below, have think there's more direct way.

dictionary<string, list<string>> resultlookup =     people.select(p => p.name).distinct().todictionary(str => str, str => new list<string>());  people.foreach(p => resultlookup[p.name].add(p.role)); 

thanks!

var dict = people.tolookup(p=>p.name, p=>p.role)   .todictionary(it=>it.key, it=>it.tolist());
