Question

I have an object

class foo {
  public int bar;
  public string s;
}

that is in a dictionary

Dictionary<String, foo> mm = new Dictionary<String, foo>();

And I want to implmeent a method using LINQ to get all values of the dictonary and return a list of all the “bar” variables. I figure this should be easy using linq, but i’ve not managed to fina relevant example.

public int[] getList() {
  return mm.Values.bar <- something like that but with linq
}

Answer 1

You can use Enumerable.Select and ToArray():

int[] bars = mm.Select(kv => kv.Value.bar).ToArray();
