定義

命名空間:
System.Xml.Serialization

傳回由型別陣列建立的 XmlSerializer 物件的陣列。

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()

參數

types
Type[]

Type 物件的陣列。

傳回

XmlSerializer[]

XmlSerializer 物件的陣列。

範例

下列範例會 FromTypes 使用 方法來傳回 物件的陣列 XmlSerializer 。 此程式碼包含三個類別定義，分別用來建立 物件的陣列 Type 。

#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

public class Instrument
{
   public string InstrumentName;

   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();
   }
}

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

備註

方法 FromTypes 可讓您有效率地建立物件的陣列 XmlSerializer ，以處理物件的陣列 Type 。 不過，當呼叫端重複呼叫此方法時，建議呼叫端快取傳回的序列化程式。
