How do I search a generic TList collection? [duplicate]

Answer 1

To be perfectly frank, and considering all the boiler plate required for a comparer based approach, it may just be simplest to write your own search routine:

type
  TActivityCategoryList = class(TList)
  public
    function Find(const Name: string): Integer;
  end;

function TActivityCategoryList.Find(const Name: string): Integer;
begin
  for Result := 0 to Count-1 do
    if Self[Result].Name=Name then
      exit;
  Result := -1;
end;
