Commenti

Se si specifica un Name valore di proprietà quando si applica l'attributo, tutti o XmlNode gli XmlElement oggetti inseriti nella matrice devono avere lo stesso nome di elemento e lo spazio dei nomi predefinito oppure viene generata un'eccezione. Se si imposta il valore della Namespace proprietà, è necessario impostare anche la Name proprietà e gli XmlElement oggetti o XmlNode devono avere anche lo stesso nome e i valori dello spazio dei nomi. Se non Name viene specificato alcun valore, gli XmlElement oggetti o XmlNode possono avere qualsiasi nome di elemento.

Quando si chiama il Deserialize metodo della XmlSerializer classe, tutti gli attributi che non hanno un membro corrispondente nell'oggetto deserializzato vengono raccolti nella matrice. Se si specifica un Name valore, la matrice contiene solo elementi XML con tale nome. Se non si specifica un Name valore, la matrice contiene tutti gli elementi che non hanno alcun membro corrispondente nella classe. Se una classe contiene più campi a cui viene applicato l'attributo, utilizzare le Name proprietà e Namespace per distinguere il contenuto delle matrici. Se tale classe (con più campi) contiene anche un campo che non dispone di valori Name di proprietà diversi , ovvero e Namespace) durante la deserializzazione, la matrice contiene tutti gli elementi XML che non sono già contenuti nelle altre matrici. Se si aggiungono più campi che non dispongono di un set di valori o di differenziazioneName, l'ultimo campo della classe contiene tutti gli elementi sconosciuti che non sono già contenuti nelle altre matrici e tutti gli altri campi sono impostati su null.Namespace

È possibile applicare più istanze di a XmlAnyElementAttribute un membro della classe, ma ogni istanza deve avere un valore di proprietà distinto Name . In alternativa, se la stessa Name proprietà è impostata per ogni istanza, è necessario impostare un valore di proprietà distinto Namespace per ogni istanza.
