XmlAttributeAttribute.AttributeName プロパティ

XML 属性の名前を取得または設定します。

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 AttributeName As
 String

Visual Basic (使用法)

Dim instance As XmlAttributeAttribute
Dim value As String

value = instance.AttributeName

instance.AttributeName = value

public string AttributeName { get;
 set; }

C++

public:
property String^ AttributeName {
    String^ get ();
    void set (String^ value);
}

/** @property */
public String get_AttributeName ()

/** @property */
public void set_AttributeName (String value)

JScript

public function get AttributeName
 () : String

public function set AttributeName
 (value : String)

プロパティ値
XML 属性の名前。既定値は、メンバ名です。

解説

既定値が使用できない場合は、AttributeName プロパティを使用して、XML 属性名を指定します。たとえば、XML 属性名がメンバ識別子としては無効である場合は、AttributeName を無効な名前に設定する一方で、識別子に対して有効な名前を使用できます。

使用例

XmlAttributeAttribute の AttributeName プロパティを設定する例を次に示します。
