Devolve um array de XmlSerializer objetos criados a partir de um array de tipos.

public:
 static cli::array <System::Xml::Serialization::XmlSerializer ^> ^ FromTypes(cli::array <Type ^> ^ types);
public static System.Xml.Serialization.XmlSerializer[] FromTypes(Type[] types);
static member FromTypes : Type[] -> System.Xml.Serialization.XmlSerializer[]
Public Shared Function FromTypes (types As Type()) As XmlSerializer()

Parâmetros

types
Type[]

Uma variedade de Type objetos.

Devoluções

XmlSerializer[]

Uma variedade de XmlSerializer objetos.

Exemplos

O exemplo seguinte utiliza o FromTypes método para devolver um array de XmlSerializer objetos. O código inclui três definições de classe que são usadas para criar um array 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

Observações

O FromTypes método permite-lhe criar eficientemente um array de XmlSerializer objetos para processar um array de Type objetos. No entanto, recomenda-se que os chamadores armazenem em cache os serializadores devolvidos quando há chamadas repetidas a este método.
