範例

以下範例序列化一個名為 Transportation 的類別實例，該類別包含一個名為 Vehicle的欄位。 SoapElementAttribute A 應用於該場。 當欄位被序列化時，XML 元素名稱為「Wheels」而非「Vehicle」。 該SerializeOverride方法創建 aSoapElementAttribute，並將 a SoapAttributes 的性質設定SoapElement為 SoapElementAttribute。 SoapAttributes將 加入 ，SoapAttributeOverrides用來產生 XmlTypeMapping。 XmlSerializer An 是用 XmlTypeMapping構造的，類別的實例Transportation也會再次序列化。 由於 SoapElementAttribute 是用來覆寫序列化，因此產生的 XML 元素名稱現在改為「Truck」而非「Wheels」。
