public XmlAnyAttributeAttribute ();

Public Sub New ()

例

次の例では、オブジェクトの XmlAnyAttributeAttribute 逆シリアル化をオーバーライドするために使用されるオブジェクトを構築します。 この例を試すには、次の XML を含む UnknownAttributes.xml という名前のファイルを作成します。

<?xml version="1.0" encoding="utf-8"?>  
<Group xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" GroupType = 'Technical' GroupNumber = '42' GroupBase = 'Red'>  
  <GroupName>MyGroup</GroupName>  
</Group>
