Ejemplos

En el ejemplo siguiente se usa el FromTypes método para devolver una matriz de XmlSerializer objetos . El código incluye tres definiciones de clase que se usan para crear una matriz de Type objetos.

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

Comentarios

El FromTypes método permite crear eficazmente una matriz de XmlSerializer objetos para procesar una matriz de Type objetos. Sin embargo, se recomienda que los autores de llamadas almacenen en caché los serializadores devueltos cuando hay llamadas repetidas a este método.
