FindComponent功能是找控件,找到就返回控件,找不到就是nil
方法一:
Image0.Picture:=(Form3.FindComponent('Image'+IntToStr(i)) as TImage).Picture;方法二:
Image0.Picture:=TImage(Form3.FindComponent('Image'+IntToStr(i))).Picture;方法三:
procedure TForm3.Button1Click(Sender: TObject);
var
aCompent: TComponent;
begin
aCompent :=Form3.FindComponent('Image'+IntToStr(i));
if aCompent <> nil then
begin
with (aCompent as TImage).Picture do
begin
Icon:=Image0.Picture.Icon;
end;
end;
