Get value from array if not out of bounds

Why not use an Array?

public object GetNamedParametersFrom(GenericObject genericObject)
{
    string[] namesFromLists = new string[genericObject.ListOfThings.Count];

    for (int i = 0; i < genericObject.ListOfThings.Count; i++)
    {
        namesFromLists[i] = genericObject.ListOfThings[i].Name;
    }

    return namesFromLists; //As you are returning an `object`, you can return `resources` array directly from this method
}

Why not use the built-in ElementAtOrDefault method from Linq?

string[] names =
    { "Hartono, Tommy", "Adams, Terry", "Andersen, Henriette Thaulow",
        "Hedlund, Magnus", "Ito, Shu" };

int index = 20;

string name = names.ElementAtOrDefault(index);
