Nesne döndüren bir üye içeren bir nesne geçersiz kılındığında tüm ad alanı bildirimlerinin tutulup tutulmayacağını belirten bir XmlSerializerNamespaces değeri alır veya ayarlar.

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

Özellik Değeri

Boolean

true ad alanı bildirimlerinin tutulması gerekiyorsa; aksi takdirde , false.

Örnekler

Aşağıdaki örnek adlı Studentbir sınıf içerir. sınıfı, bir nesnesi döndüren adlı MyNamespaces bir XmlSerializerNamespaces üye içerir. Örnek, sınıfın bir XmlAttributes örneğine XmlAttributeOverrides eklenen bir nesne oluşturur. Xmlns özelliği olarak ayarlanır trueve nesnenin seri hale getirilmesi Student geçersiz kılındığında ad alanlarının korunmasını sağlarXmlSerializer.
