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;
