속성 값
XML 요소의 네임스페이스입니다.
예제
다음 예제에서는 두 멤버가 포함된 클래스의 Library
인스턴스를 직렬화합니다. 하나는 책 제목을 포함하고 다른 하나는 주기적인 제목을 포함합니다. 두 XML 요소 모두 이름이 지정 Titles
되지만 각각 다른 접두사도 포함됩니다. 이 예제에는 두 요소 이름을 한정하는 데 사용되는 네임스페이스 및 접두사도 포함된 클래스의 인스턴스 XmlSerializerNamespaces 가 포함되어 있습니다.

설명
이 Namespace 속성을 사용하면 정규화된 XML 요소 이름을 만들 수 있습니다. 이 속성은 Namespace XML의 네임스페이스라는 1999년 World Wide Web 컨소시엄 문서에 있는 XML 네임스페이스를 만드는 규칙을 준수합니다.
접두사와 연결된 네임스페이스를 만들려면 XML 문서에 사용되는 네임스페이스 및 접두사가 포함된 클래스의 XmlSerializerNamespaces 인스턴스를 만들어야 합니다. 각각 XmlArrayAttribute에 대한 네임스페이스를 설정할 때 해당 네임스페이스는 해당 네임스페이스의 네임스페이스 중 하나와 XmlSerializerNamespaces일치해야 합니다. XML이 생성되면 각 배열에 지정된 네임스페이스와 연결된 접두사로 올바르게 접두사로 지정됩니다.
