Voorbeelden
In het volgende voorbeeld wordt de FromTypes methode gebruikt om een matrix met XmlSerializer objecten te retourneren. De code bevat drie klassedefinities die elk worden gebruikt om een matrix met Type objecten te maken.
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
Opmerkingen
Met de FromTypes methode kunt u efficiënt een matrix met objecten maken voor het verwerken van XmlSerializer een matrix met Type objecten. Het wordt echter aanbevolen voor bellers om de geretourneerde serializers in de cache te plaatsen wanneer er herhaalde aanroepen naar deze methode worden uitgevoerd.
