注解

方法 Serialize 将对象的公共字段和读/写属性转换为 XML。它不转换方法、索引器、私有字段或只读属性。

在参数中 xmlWriter ，指定派生自抽象 XmlWriter 类的对象。 XmlTextWriter派生自 XmlWriter。

注意

XmlSerializer无法序列化以下内容：的ArrayList数组和的List<T>数组。

member this.Serialize : System.Xml.XmlWriter * obj * System.Xml.Serialization.XmlSerializerNamespaces * string * string -> unit

Public Sub Serialize (xmlWriter As XmlWriter, o As Object, namespaces As XmlSerializerNamespaces, encodingStyle As String, id As String)

参数

xmlWriter: XmlWriter

用于编写 XML 文档的 XmlWriter。

o: Object

要序列化的对象。

namespaces: XmlSerializerNamespaces

XmlSerializerNamespaces 的实例，其中包含要使用的命名空间和前缀。

encodingStyle: String

该文档中使用的编码。

id: String

对于 SOAP 编码消息，这是用于生成 id 特性的基。

注解

id 参数提供用于创建 SOAP ID 的基字符串。默认情况下，它们是“id1”、“id2”等。但如果参数设置为“myBase”，则生成的值为“myBaseid1”、“myBaseid2”等。此功能用于在整个 SOAP 消息中创建唯一的 ID 值。
