XmlAttributes.XmlType プロパティ

.NET Framework クラス ライブラリ リファレンス

XmlAttributes.XmlType プロパティ

XmlTypeAttribute が適用されているクラスを XmlSerializer がシリアル化する方法を指定するオブジェクトを取得または指定します。

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 Property XmlType As
 XmlTypeAttribute

Visual Basic (使用法)

Dim instance As XmlAttributes
Dim value As XmlTypeAttribute

value = instance.XmlType

instance.XmlType = value

C#

public XmlTypeAttribute XmlType { get; set;
 }

C++

public:
property XmlTypeAttribute^ XmlType {
    XmlTypeAttribute^ get ();
    void set (XmlTypeAttribute^ value);
}

J#

/** @property */
public XmlTypeAttribute get_XmlType ()

/** @property */
public void set_XmlType (XmlTypeAttribute value)

JScript

public function get XmlType
 () : XmlTypeAttribute

public function set XmlType
 (value : XmlTypeAttribute)

プロパティ値
クラス宣言に適用された XmlTypeAttribute をオーバーライドする XmlTypeAttribute。

解説

XmlTypeAttribute を使用して、XmlSerializer による型のシリアル化方法を制御できます。たとえば、既定では、型がシリアル化されるときは、XmlSerializer はクラス名を XML 要素名として使用します。XmlTypeAttribute を作成し、それに XmlType プロパティを設定し、XmlAttributeOverrides オブジェクトを作成することによって、XML 要素名を変更できます。

使用例

XmlTypeAttribute オブジェクトを作成し、そのオブジェクトを XmlAttributes オブジェクトの XmlType プロパティに代入する例を次に示します。

Imports System.IO
Imports System.Xml.Serialization
