How to save and load captions of several labels?

Question

I need to save and load captions of several labels. I tried use TMemo for this:

procedure TForm1.Button1Click(Sender: TObject);    
begin    
  if SaveDialog1.Execute then
  begin    
     Memo1.Lines.SaveToFile(saveDialog1.FileName+'.txt');    
  end;    
end;


procedure TForm1.Button2Click(Sender: TObject);
begin
  if OpenDialog1.Execute then
  begin
    Memo1.Lines.LoadFromFile(OpenDialog1.FileName);
  end;
end;

But I don’t know how to set and get specific data of Label1, Label2, etc on the TMemo.

Based on this idea later I will use other components as TEdit.

I modified a little this code according to my requirements.

procedure TForm1.ButtonSaveClick(Sender: TObject);
var
  I: Integer;
  Strings: TStringList;
begin
  if SaveDialog1.Execute then
  begin
  Strings := TStringList.Create;
  try
    for I := 0 to ComponentCount - 1 do
      begin
      if Components[I] is TLabel then
        Strings.Values[Components[I].Name] := TLabel(Components[I]).Caption;
      if Components[I] is TEdit then
        Strings.Values[Components[I].Name] := TEdit(Components[I]).Text;
    end;
    Strings.SaveToFile(SaveDialog1.FileName);
  finally
    Strings.Free;
  end;
end;
end;

procedure TForm1.ButtonLoadClick(Sender: TObject);
var
  I: Integer;
  Control: TComponent;
  Strings: TStringList;
begin
  if OpenDialog1.Execute then
  begin
  Strings := TStringList.Create;
  try
    Strings.LoadFromFile(OpenDialog1.FileName);
    for I := 0 to Strings.Count - 1 do
    begin
      Control := FindComponent(Strings.Names[I]);
      if Control is TLabel then
        TLabel(Control).Caption := Strings.ValueFromIndex[I];
      if Control is TEdit then
        TEdit(Control).Text := Strings.ValueFromIndex[I];
    end;
  finally
    Strings.Free;
    end;
  end;
end;
