MessageQueryTable<TItem> MessageQueryTable<TItem> MessageQueryTable<TItem> MessageQueryTable<TItem> Class

Definizione

Gestisce una raccolta di oggetti query del messaggio.Manages a collection of message query objects.

generic <typename TItem>
public ref class MessageQueryTable : System::Collections::Generic::ICollection<System::Collections::Generic::KeyValuePair<System::ServiceModel::Dispatcher::MessageQuery ^, TItem>>, System::Collections::Generic::IDictionary<System::ServiceModel::Dispatcher::MessageQuery ^, TItem>, System::Collections::Generic::IEnumerable<System::Collections::Generic::KeyValuePair<System::ServiceModel::Dispatcher::MessageQuery ^, TItem>>

Public Class MessageQueryTable(Of TItem)
Implements ICollection(Of KeyValuePair(Of MessageQuery, TItem)), IDictionary(Of MessageQuery, TItem), IEnumerable(Of KeyValuePair(Of MessageQuery, TItem))

Parametri di tipo

TItem

Tipo di valori restituiti dalle query.The type of the values returned by the queries.

Implementazioni

Esempi

Nell'esempio seguente viene effettuata la creazione di un messaggio e delle query del messaggio XPath.The following example creates a message and XPath message queries. Le query vengono valutate dagli oggetti XPathMessageQuery contenuti in un oggetto XPathMessageQueryCollection.The queries are evaluated by the XPathMessageQuery objects contained in an XPathMessageQueryCollection object. I risultati di ogni query vengono testati utilizzando la proprietà ResultType della classe XPathResult.The results of each query are tested using the ResultType property of the XPathResult class. Rimuovere il commento dal codice alternativo per vedere la funzionalità simile illustrata utilizzando MessageQueryTable<TItem>.Uncomment the alternate code to see similar functionality demonstrated using the MessageQueryTable<TItem>.
