XmlAttributes.Xmlns 속성

정의

네임스페이스:

System.Xml.Serialization

어셈블리:

netstandard.dll, System.Xml.XmlSerializer.dll

Source:

XmlAttributes.cs

개체를 반환 XmlSerializerNamespaces 하는 멤버를 포함하는 개체가 재정의될 때 모든 네임스페이스 선언을 유지할지 여부를 지정하는 값을 가져오거나 설정합니다.

public:
 property bool Xmlns { bool get(); void set(bool value); };

public bool Xmlns { get; set; }

member this.Xmlns : bool with get, set

Public Property Xmlns As Boolean

속성 값

Boolean

true네임스페이스 선언을 유지해야 하면 이고, 그렇지 않으면 . false

예제

다음 예제에는 이름이 인 클래스가 포함되어 있습니다. 클래스에는 개체를 반환 XmlSerializerNamespaces 하는 명명 MyNamespaces 된 멤버가 포함됩니다. 이 예제에서는 클래스의 인스턴스에 추가되는 개체를 XmlAttributeOverrides 만듭니다XmlAttributes. 개체 Xmlns 의 serialization이 재정의 Student 될 때 네임스페이스를 유지하도록 지시 XmlSerializer 하는 속성이 설정true됩니다.
