Comentários
Tipos de conteúdo são projetados para ajudar os usuários a organizar seu conteúdo do SharePoint de uma maneira mais significativa. Um tipo de conteúdo é um conjunto de configurações que você deseja aplicar a uma determinada categoria de conteúdo reutilizável. Tipos de conteúdo permitem que você gerencie os metadados e os comportamentos de um tipo de documento ou item de maneira centralizada e reutilizável.
Para obter mais informações, consulte Introduction to Content Types.
Examples
O exemplo a seguir é um aplicativo de console que cria um tipo de conteúdo e o adiciona à coleção de tipo de conteúdo do site. Em seguida, o exemplo cria um campo (coluna) e links campo para o novo tipo de conteúdo. Finalmente, o exemplo cria uma lista e adiciona o novo tipo de conteúdo para a coleção de tipo de conteúdo que pertence à lista.
Antes de executar o aplicativo, você precisa adicionar uma referência ao Microsoft.Sharepoint.dll ao seu projeto.
