Matriz de objetos XmlSerializer.
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.Xml.dll>
#using <System.dll>
using namespace System;
using namespace System::IO;
using namespace System::Xml::Serialization;
/* Three classes are included here. Each one will
be used to create three XmlSerializer objects. */
public ref class Instrument
{
public:
String^ InstrumentName;
};
public ref class Player
{
public:
String^ PlayerName;
};
public ref class Piece
{
public:
String^ PieceName;
};
void GetSerializers()
{
// Create an array of types.
array<Type^>^types = gcnew array<Type^>(3);
types[ 0 ] = Instrument::typeid;
types[ 1 ] = Player::typeid;
types[ 2 ] = Piece::typeid;
// Create an array for XmlSerializer objects.
array<XmlSerializer^>^serializers = gcnew array<XmlSerializer^>(3);
serializers = XmlSerializer::FromTypes( types );
// Create one Instrument and serialize it.
Instrument^ i = gcnew Instrument;
i->InstrumentName = "Piano";
// Create a TextWriter to write with.
TextWriter^ writer = gcnew StreamWriter( "Inst.xml" );
serializers[ 0 ]->Serialize( writer, i );
writer->Close();
}
int main()
{
GetSerializers();
}
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 Test();
t.GetSerializers();
}
public void GetSerializers()
{
// Create an array of types.
Type[]types = new Type[3];
types[0] = typeof(Instrument);
types[1] = typeof(Player);
types[2] = 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();
}
}

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 haya llamadas repetidas a este método.
