XmlSerializer.FromTypes-Methode

Gibt ein Array von XmlSerializer-Objekten zurück, das aus einem Array von Typen erstellt wurde.

Namespace: System.Xml.Serialization
Assembly: System.Xml (in system.xml.dll)

Syntax

'Declaration
Public Shared Function FromTypes ( _
    types As Type() _
) As XmlSerializer()
'Usage
Dim types As Type()
Dim returnValue As XmlSerializer()

returnValue = XmlSerializer.FromTypes(types)

public static XmlSerializer[] FromTypes (
    Type[] types
)

public:
static array<XmlSerializer^>^ FromTypes (
    array<Type^>^ types
)

public static XmlSerializer[] FromTypes (
    Type[] types
)

public static function FromTypes (
    types : Type[]
) : XmlSerializer[]

Parameter

• types
  Ein Array von Type-Objekten.

Rückgabewert

Ein Array von XmlSerializer-Objekten.

Hinweise

Mithilfe der FromTypes-Methode können Sie ein Array von XmlSerializer-Objekten für die Verarbeitung eines Arrays von Type-Objekten effizient erstellen.

Beispiel

Im folgenden Beispiel wird mithilfe der FromTypes-Methode ein Array von XmlSerializer-Objekten zurückgegeben. Der Code enthält drei Klassendefinitionen, die jeweils zum Erstellen eines Arrays von Type-Objekten verwendet werden.

Imports System
Imports System.IO
Imports System.Xml.Serialization


' Three classes are included here. Each one will
' be used to create three XmlSerializer objects. 

Public Class Instrument
    Public InstrumentName As String
End Class

Public Class Player
    Public PlayerName As String
End Class

Public Class Piece
    Public PieceName As String
End Class

Public Class Test
    
    Public Shared Sub Main()
        Dim t As New Test()
        t.GetSerializers()
    End Sub    
    
    Public Sub GetSerializers()
        ' Create an array of types.
        Dim types(3) As Type
        types(0) = GetType(Instrument)
        types(1) = GetType(Player)
        types(2) = GetType(Piece)
        
        ' Create an array for XmlSerializer objects.
        Dim serializers(3) As XmlSerializer
        serializers = XmlSerializer.FromTypes(types)
        ' Create one Instrument and serialize it.
        Dim i As New Instrument()
        i.InstrumentName = "Piano"
        ' Create a TextWriter to write with.
        Dim writer As New StreamWriter("Inst.xml")
        serializers(0).Serialize(writer, i)
        writer.Close()

End Class
