static member FromTypes : Type[] -> System.Xml.Serialization.XmlSerializer[]
Public Shared Function FromTypes (types As Type()) As XmlSerializer()

Parameter

Type[]

Ein Array von Type-Objekten.An array of Type objects.

Gibt zurück

Ein Array von XmlSerializer-Objekten.An array of XmlSerializer objects.

Beispiele

Im folgenden Beispiel wird die FromTypes Methode, um ein Array von zurückzugeben XmlSerializer Objekte.The following example uses the FromTypes method to return an array of XmlSerializer objects. Der Code enthält drei Klassendefinitionen, die, die jeweils verwendet werden, erstellen Sie ein Array von Type Objekte.The code includes three class definitions that are each used to create an array of Type objects.

Hinweise

Die FromTypes Methode können Sie effizient erstellen Sie ein Array von XmlSerializer Objekte für die Verarbeitung eines Arrays von Type Objekte.The FromTypes method allows you to efficiently create an array of XmlSerializer objects for processing an array of Type objects. Es wird jedoch empfohlen, für Aufrufer der zurückgegebenen Serialisierungsprogramme zwischengespeichert, wenn wiederholte Aufrufe dieser Methode vorhanden sind.However, it is recommended for callers to cache the returned serializers when there are repeated calls to this method.
