Question

I am trying to add following values to

procedure TForm1.FormCreate(Sender: TObject);
var
  md: TDictionary<string, string>;
  s, v: string;
begin
  md := TDictionary<string, string>.Create;
  try
    s := 'orange';
    v := 'fruit';
    md.Add(s, v);

    s := 'orange ';
    v := 'color';
    md.Add(s, v);

    ShowMessage(IntToStr(md.Count));
  finally
    md.Free;
  end;
end;

I know this is duplicate but if you look at second orange, you can see a space at the end. I think Delphi trims the value but it shouldn’t.

Does anyone know solution of this problem?

Thanks,

Answer 1

This code shows a message box containing the number 2 on all known versions of Delphi. That is exactly as is expected and the TDictionary code most certainly does not trim your keys when comparing for equality.
