Примеры

В следующем примере кода показано создание ImageList, добавление изображений в Images свойство , задание ImageSize свойства и использование Draw метода . Чтобы запустить этот пример, поместите его в форму, содержащую кнопку с именем Button1. В примере предполагается наличие FeatherTexture.bmp и Gone Fishing.bmp в c:\Windows\. Измените пример соответствующим образом, если растровые изображения не существуют в системе или находятся в другом расположении.
