Comentarios
Tipos de contenido están diseñados para ayudar a los usuarios a organizar su contenido de SharePoint de manera más significativa. Un tipo de contenido es una colección de configuración que se va a aplicar a una categoría determinada de contenido reutilizable. Tipos de contenido permiten administrar los metadatos y los comportamientos de un tipo de documento o elemento de una manera centralizada y reutilizable.
Para obtener más información, vea Introduction to Content Types.
Ejemplos
En el siguiente ejemplo es una aplicación de consola que crea un tipo de contenido y lo agrega a la colección de tipo de contenido de sitio. A continuación, en el ejemplo se crea un campo (columna) y se vincula el campo para el nuevo tipo de contenido. Por último, en el ejemplo se crea una lista y agrega el nuevo tipo de contenido a la colección de tipo de contenido que pertenece a la lista.
Antes de ejecutar la aplicación, se debe agregar una referencia a Microsoft.Sharepoint.dll a su proyecto.
