XmlTextAttribute コンストラクタ

.NET Framework クラス ライブラリ リファレンス

XmlTextAttribute コンストラクタ (Type)

XmlTextAttribute クラスの新しいインスタンスを初期化します。

名前空間: System.Xml.Serialization
アセンブリ: System.Xml (system.xml.dll 内)
構文

Visual Basic (宣言)

Public Sub New ( _
    type As Type _
)

Visual Basic (使用法)

Dim type As Type

Dim instance As New XmlTextAttribute(type)

C#

public XmlTextAttribute (
    Type type
)

C++

public:
XmlTextAttribute (
    Type^ type
)

J#

public XmlTextAttribute (
    Type type
)

JScript

public function XmlTextAttribute (
    type : Type
)

パラメータ

type

シリアル化するメンバの Type。

解説

XmlSerializer がパブリック フィールドまたはパブリックな読み書き可能プロパティをシリアル化する方法をオーバーライドするには、XmlAttributes オブジェクトを作成し、その XmlText プロパティに XmlTextAttribute オブジェクトを設定します。詳細については、XmlAttributeOverrides クラスのトピックを参照してください。
