Contoh

Contoh berikut menggunakan FromTypes metode untuk mengembalikan array XmlSerializer objek. Kode ini mencakup tiga definisi kelas yang masing-masing digunakan untuk membuat array Type objek.

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

Keterangan

Metode ini FromTypes memungkinkan Anda membuat array XmlSerializer objek secara efisien untuk memproses array Type objek. Namun, disarankan bagi penelepon untuk menyimpan serializer yang dikembalikan ketika ada panggilan berulang ke metode ini.
