Comentários

Enumerando a coleção em C# ou Microsoft Visual Basic

Um ResourceQualifierVectorView é enumerável, portanto, você pode usar a sintaxe específica da linguagem, como foreach em C# para enumerar os itens na coleção. O compilador faz a conversão de tipo para você e você não precisará converter IEnumerable<ResourceQualifier> explicitamente. Se você precisar converter explicitamente, por exemplo, se quiser chamar GetEnumerator, converta para IEnumerable<T> com uma restrição ResourceQualifier .

Propriedades

Size

Obtém o número de objetos ResourceQualifier na exibição.

Métodos

First()

Retorna um iterador para enumerar os itens na exibição.

GetAt(UInt32)

Retorna o ResourceQualifier no índice especificado na exibição.

GetMany(UInt32, ResourceQualifier[])

Retorna os objetos ResourceQualifier que começam no índice especificado na exibição.

IndexOf(ResourceQualifier, UInt32)

Retorna o índice de um ResourceQualifier especificado na exibição.
