Özellik Değeri

Bir XmlTextAttribute ortak özelliğin veya alanın varsayılan serileştirmesini geçersiz kılan.

Örnekler

Aşağıdaki örnek adlı bir alan Commentiçeren adlı Groupsınıfı seri hale getirmektedir. Alanı seri hale getirmenin XmlSerializer varsayılan yolunu geçersiz kılmak için örnek bir XmlAttributeOverrides ve XmlAttributes nesnesi oluşturur. Örnek daha sonra özelliğine XmlText atadığı bir XmlTextAttribute nesnesi oluşturur ve nesneyi (XML metni olarak serileştirilecek alanın adıyla) nesnesine XmlAttributeOverrides eklerXmlAttributes. Son olarak örnek nesnesini kullanarak XmlAttributeOverrides bir XmlSerializer oluşturur.

Açıklamalar

Varsayılan olarak, bir ortak alan veya ortak okuma/yazma özelliği tarafından XmlSerializerxml öğesi olarak serileştirilir. Ancak, alana veya özelliğe uygulayarak XmlTextAttribute alan veya özelliğin XML metni olarak seri hale getirilmeye zorlanabilir.

Bir alan veya özelliğin (dizi döndürmeyen) varsayılan serileştirmesini geçersiz kılmak için, bir XmlTextAttribute oluşturun ve bunu bir XmlAttributes nesnenin XmlText özelliğine atayın. XmlAttributes Nesnesini bir XmlAttributeOverrides nesneye ekleyin ve geçersiz kılınan alanı veya özelliği içeren nesnenin türünü ve geçersiz kılınan alan veya özelliğin adını belirtin.

Şunlara uygulanır
