XmlSerializer가 열거형 멤버를 serialize하는 방식을 지정하는 개체를 가져오거나 설정합니다.

public:
 property System::Xml::Serialization::XmlEnumAttribute ^ XmlEnum { System::Xml::Serialization::XmlEnumAttribute ^ get(); void set(System::Xml::Serialization::XmlEnumAttribute ^ value); };

public System.Xml.Serialization.XmlEnumAttribute XmlEnum { get; set; }

public System.Xml.Serialization.XmlEnumAttribute? XmlEnum { get; set; }

member this.XmlEnum : System.Xml.Serialization.XmlEnumAttribute with get, set

Public Property XmlEnum As XmlEnumAttribute

속성 값

XmlEnumAttribute

XmlEnumAttribute가 열거형 멤버를 serialize하는 방식을 지정하는 XmlSerializer입니다.

예제

다음 예제에서는 라는 두 개의 클래스를 직렬화 Food 고 FoodType입니다. FoodType 재정의 되는 두 개의 열거형을 포함 하는 클래스를 만듭니다 각 열거에 대 한는 XmlEnumAttribute 에 할당 되는 개체를 XmlEnum 의 속성은 XmlAttributes 개체. 예제에서는 그런를 XmlAttributes 개체를 XmlAttributeOverrides 개체를 만드는 데 사용 되는 XmlSerializer합니다.

설명

재정의 하려는 각 식별자를 만들어야 합니다는 XmlAttributes 개체를 설정 합니다 XmlEnum 속성을는 XmlEnumAttribute 식별자를 재정의 하 합니다. 추가 합니다 XmlAttributes 개체를 XmlAttributeOverrides 개체를 모두 지정를 Type 열거형 및 재정의 된 멤버 이름을 포함 하는 클래스의 합니다.
