Gibt zurück
Ein Array von XmlSerializer-Objekten.

Beispiele
Im folgenden Beispiel wird die FromTypes Methode verwendet, um ein Array von XmlSerializer Objekten zurückzugeben. Der Code enthält drei Klassendefinitionen, die jeweils zum Erstellen eines Arrays von Type Objekten verwendet werden.
using System;
using System.IO;
using System.Xml.Serialization;
/* Three classes are included here. Each one will
be used to create three XmlSerializer objects. */
public class Instrument
{
public string InstrumentName;
}
public class Player
{
public string PlayerName;
}
public class Piece
{
public string PieceName;
}
public class Test
{
public static void Main()
{
Test t = new();
t.GetSerializers();
}
public void GetSerializers()
{
// Create an array of types.
Type[] types = [typeof(Instrument), typeof(Player), typeof(Piece)];
// Create an array for XmlSerializer objects.
XmlSerializer[] serializers = new XmlSerializer[3];
serializers = XmlSerializer.FromTypes(types);
// Create one Instrument and serialize it.
Instrument i = new Instrument();
i.InstrumentName = "Piano";
// Create a TextWriter to write with.
TextWriter writer = new StreamWriter("Inst.xml");
serializers[0].Serialize(writer, i);
writer.Close();
}
}
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 Sub
End Class
Hinweise
Mit der FromTypes Methode können Sie effizient ein Array von XmlSerializer Objekten zum Verarbeiten eines Arrays von Type Objekten erstellen. Es wird jedoch empfohlen, dass Aufrufer die zurückgegebenen Serialisierer zwischenspeichern, wenn wiederholte Aufrufe dieser Methode vorhanden sind.
