Örnekler

Aşağıdaki örnek yeni XmlAnyElementAttribute bir oluşturur ve özelliği aracılığıyla erişilen nesne koleksiyonuna XmlAnyElements ekler. daha XmlAttributes sonra , oluşturmak için kullanılan öğesine XmlAttributeOverridesXmlSerializereklenir. XmlSerializer, bir nesneyi seri hale getirmek veya seri durumdan çıkartmak için kullanılır. özelliğini kullanmanın etkisini görmek için yönteminde XmlAnyElementAttributes yöntemini Main çalıştırarak SerializeObject UnknownElements.xml adlı bir XML belgesi oluşturun. Sonuçta elde edilen belgeyi diğer (bilinmeyen) öğeleri içerecek şekilde düzenleyin. yöntemindeki çağrıyı SerializeObjectMain açıklama satırı yapma ve bilinmeyen herhangi bir XML öğesinin adını ve değerini yazdıran yöntemi çağrısının DeserializeObject açıklamasını kaldırın.
