Gibt ein Array von XmlSerializer-Objekten zurück, das aus einem Array von Typen erstellt wurde.

public:
 static cli::array <System::Xml::Serialization::XmlSerializer ^> ^ FromTypes(cli::array <Type ^> ^ types);

public static System.Xml.Serialization.XmlSerializer[] FromTypes (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()

Parameter

types: Type[]

Ein Array von Type-Objekten.

Gibt zurück

XmlSerializer[]

Ein Array von XmlSerializer-Objekten.

Beispiele

Im folgenden Beispiel wird die FromTypes Methode verwendet, um ein Array von XmlSerializer Objekten zurückzugeben. Der Code enthält drei Klassendefinitionen, die jeweils zum Erstellen eines Arrays von Type Objekten verwendet werden.

#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();
   }
}

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

Public Class Player
    Public PlayerName As String
End Class

Public Class Test
    
    Public Shared Sub Main()

    End Sub    
    
    Public Sub GetSerializers()
        ' Create an array of types.
        Dim types(3) As Type
        types(0) = GetType(Instrument)

        ' 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

Hinweise

Mit der FromTypes Methode können Sie effizient ein Array von Objekten für die Verarbeitung eines Arrays von Type XmlSerializer Objekten erstellen. Es wird jedoch empfohlen, aufrufer die zurückgegebenen Serializer zwischenzuspeichern, wenn wiederholte Aufrufe dieser Methode vorhanden sind.
