Classe ImageList.ImageCollection

Encapsula a coleção de Image objetos em um ImageList.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (em System.Windows.Forms.dll)

public sealed class ImageCollection : IList, 
	ICollection, IEnumerable

Isso é usado para gerenciar as imagens no ImageList programaticamente, fornecendo métodos para adicionar e remover objetos de imagem.

O exemplo de código a seguir mostra como selecionar, remover e exibir imagens, da Images propriedade das ImageList classe, que é um ImageList.ImageCollection Digite.
