 void Remove(System::Web::UI::WebControls::HotSpot ^ spot);

Exemplos

O exemplo de código a seguir demonstra como adicionar programaticamente dois CircleHotSpot objetos a um ImageMap controle . Depois que os dois CircleHotSpot objetos são adicionados à HotSpotCollection coleção, o Remove método é usado para excluir Circle1 da coleção. Para que este exemplo funcione corretamente, você deve fornecer sua própria imagem para a ImageUrl propriedade e atualizar o caminho para a imagem adequadamente para que o aplicativo possa localizá-la.
