Returns
An array of XmlSerializer objects.
Examples
The following example uses the FromTypes method to return an array of XmlSerializer objects. The code includes three class definitions that are each used to create an array of Type objects.
#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 static void Main()
{

}
public void GetSerializers()

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();
}
}

' 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()

' Create a TextWriter to write with.
Dim writer As New StreamWriter("Inst.xml")
serializers(0).Serialize(writer, i)
writer.Close()
End Sub
End Class
Remarks
The FromTypes method allows you to efficiently create an array of XmlSerializer objects for processing an array of Type objects. However, it is recommended for callers to cache the returned serializers when there are repeated calls to this method.
