定义

命名空间:
System.Xml.Serialization
程序集:
System.Xml.XmlSerializer.dll
程序集:
System.Xml.dll
程序集:
netstandard.dll

返回从类型数组创建的 XmlSerializer 对象的数组。

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()

参数

types
Type[]

一个 Type 对象数组。

返回

XmlSerializer[]

一个 XmlSerializer 对象数组。

示例

以下示例使用 FromTypes 该方法返回对象的数组 XmlSerializer 。 该代码包含三个类定义，每个定义用于创建对象数组 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
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
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

注解

通过此方法 FromTypes ，可以有效地创建对象数组 XmlSerializer 以处理对象数组 Type 。 但是，当对此方法进行重复调用时，建议调用方缓存返回的序列化程序。
