Ask about the issue of memory release. (The dynamically created controls are saved in Tlist)

xingji55

I dynamically add some controls (TButton, TEdit, TLabel...) when the strategy program is running.
And save them in Tlist. Please teach me how to release these controls.

I want to use the RTTI method to obtain the ClassName of the object according to the object pointed to by list[i].
Get the Destroy procedure of the object according to ClassName, and then call the procedure.
Is there a problem with this? Please expert guidance.

for i:=0 to List1.Count-1 do
begin
FreeAndNil(List1.Items[i]);
List1.Delete(i);
end;

for I:=T.Count-1 downto 0 do
begin
  TObject(T.Items[i]).Free;
  T.Delete(I);
end;
end;
