Comentarios

Sitios de enlazan un Component a un Container y habilitar la comunicación entre ellos, así como proporcionar una forma para el contenedor administrar sus componentes.Sites bind a Component to a Container and enable communication between them, as well as provide a way for the container to manage its components.

Los sitios también pueden actuar como un repositorio para obtener información específica del contenedor, por componente, como el nombre del componente.Sites can also serve as a repository for container-specific, per-component information, such as the component name. Para obtener más información acerca de los componentes, consulte programar con componentes.For more information about components, see Programming with Components.

Notas a los implementadores

Para que sea un sitio, una clase debe implementar la ISite interfaz.To be a site, a class must implement the ISite interface.
