次の例では、UnknownNodeのイベント、XmlSerializerを呼び出すときに発生する不明な XML ノードのさまざまなプロパティを印刷する、XmlSerializerクラスのDeserializeメソッド。The following example uses the UnknownNode event of the XmlSerializer to print various properties of an unknown XML node that is encountered when calling the XmlSerializer class's Deserialize method.
