예제

다음 예제에서는 라는 두 개의 클래스를 직렬화 Food 고 FoodType입니다. 클래스에는 FoodType 재정의되는 두 개의 열거형이 포함되며, 각 열거형에 대해 개체의 XmlAttributes 속성에 XmlEnum 할당된 개체를 만드는 XmlEnumAttribute 예제입니다. 예제에서는 그런를 XmlAttributes 개체를 XmlAttributeOverrides 개체를 만드는 데 사용 되는 XmlSerializer합니다.

설명

기존 열거형을 재정의하는 데 사용할 XmlEnumAttribute 수 있습니다.

참고

더 긴 XmlEnumAttribute대신 코드에서 단어를 XmlEnum 사용할 수 있습니다.

• Deserialize(Stream)
• XmlSerializer

XmlEnumAttribute(String)

XmlEnumAttribute 클래스의 새 인스턴스를 초기화하고 XmlSerializer가 열거형을 직렬화하거나 역직렬화할 때 생성하거나 인식하는 XML 값을 지정합니다.

public:
 XmlEnumAttribute(System::String ^ name);

public XmlEnumAttribute (string name);

public XmlEnumAttribute (string? name);

new System.Xml.Serialization.XmlEnumAttribute : string -> System.Xml.Serialization.XmlEnumAttribute

Public Sub New (name As String)

매개 변수

name

String

열거형 멤버의 재정의 이름입니다.

예제

다음 예제에서는 XmlEnumAttribute 열거형의 멤버에 적용 합니다. XmlSerializer 이 열거형에 대한 XML 데이터를 생성하는 경우 데이터는 속성 값을 Name 준수합니다.

public enum class EmployeeStatus
{
   [XmlEnum("Single")]
   One,
   [XmlEnum("Double")]
   Two,
   [XmlEnum("Triple")]
   Three
};

public enum EmployeeStatus
{
   [XmlEnum("Single")]
   One,
   [XmlEnum("Double")]
   Two,
   [XmlEnum("Triple")]
   Three
}

Public Enum EmployeeStatus
   <XmlEnumAttribute("Single")> One
   <XmlEnumAttribute("Double")> Two
   <XmlEnumAttribute("Triple")> Three
End Enum
