.NET Framework クラス ライブラリ リファレンス

XmlTextWriter.WriteEndAttribute メソッド

前の WriteStartAttribute 呼び出しを閉じます。

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

Visual Basic (宣言)

Public Overrides Sub WriteEndAttribute

Visual Basic (使用法)

Dim instance As XmlTextWriter

instance.WriteEndAttribute

C#

public override void WriteEndAttribute ()

C++

public:
virtual void WriteEndAttribute () override

J#

public void WriteEndAttribute ()

JScript

public override function WriteEndAttribute
 ()

解説

メモ
Microsoft .NET Framework version 2.0 リリースでは、System.Xml.XmlWriter.Create メソッドと XmlWriterSettings クラスを使用して XmlWriter インスタンスを作成することをお勧めします。これにより、このリリースで導入されたすべての新機能を十分に活用できます。詳細については、「XML ライタの作成」を参照してください。

WriteStartAttribute を呼び出すと、このメソッドで属性を閉じることができます。

WriteStartAttribute を再び呼び出すか、WriteAttributeStringまたは WriteEndElement を呼び出して、属性を閉じることもできます。
