Question

Here’s what I’m trying to do:

ObjectA
{
    int ID;
    string name;
}

I want to convert Dictionary to List where the strings in the list are the .name values of the ObjectAs in the dictionary. Obviously I could manually iterate over the dictionary values and build the list that way, but I was hoping there’d be a simpler or faster way in C# / .NET. A LINQ solution is fine, if it’s simpler and faster than/as fast as:

List<string> aNames = new List<string>();
foreach(ObjectA a in DictionaryA.Values)
aNames.Add(a.name);

Here’s the non-query-expression form of Matthew’s answer:

var names = DictionaryA.Values.Select(x => x.name).ToList();

(I tend not to use query expressions when I’m just doing a single select or a single where, especially if I also need to call another method such as ToList.)

Alternatively:

var names = DictionaryA.Select(x => x.Value.name).ToList();
