備註

方法 Serialize 會將物件的公用欄位和讀取/寫入屬性轉換成 XML。 它不會轉換方法、索引子、私用欄位或唯讀屬性。

在 參數中 xmlWriter ,指定衍生自抽象 XmlWriter 類的物件。 XmlTextWriter衍生自 XmlWriter

注意

XmlSerializer無法序列化下列專案:的 ArrayList 陣列和 的 List<T> 陣列。

XmlSerializerNamespaces 執行個體,包含要使用的命名空間和前置詞。

encodingStyle
String

文件中使用的編碼方式。

id
String

若為 SOAP 編碼的訊息,則為用於產生 ID 屬性的基底。

備註

id參數會提供用來建立 SOAP 識別碼的基底字串。 根據預設,這些是 「id1」、「id2」 等等。 但是,如果參數設定為 「myBase」,則產生的值為 「myBaseid1」、「myBaseid2」 等等。 這項功能可用來在整個 SOAP 訊息中建立唯一識別碼值。
