XmlSerializer.FromTypes メソッド

型の配列から作成された、 XmlSerializer オブジェクトの配列を返します。

Public Shared Function FromTypes( _
   ByVal types() As Type _) As XmlSerializer()
[C#]
public static XmlSerializer[] FromTypes(Type[] types);
[C++]
public: static XmlSerializer* FromTypes(Type* types[]) [];
[JScript]
public static function FromTypes(
   types : Type[]) : XmlSerializer[];

パラメータ

• types
  Type オブジェクトの配列。

戻り値

XmlSerializer オブジェクトの配列。

解説

FromTypes メソッドを使用することで、 Type オブジェクトの配列を処理するための XmlSerializer オブジェクトの配列を効率的に作成できます。

使用例

[Visual Basic, C#, C++] FromTypes メソッドを使用して、 XmlSerializer オブジェクトの配列を返す例を次に示します。このコードには 3 つのクラス定義が含まれており、それぞれを使用して Type オブジェクトの配列を作成します。

 
Imports System
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)

        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 Class
