XmlArrayAttribute.ElementName 属性

定义

命名空间:

System.Xml.Serialization

程序集:

System.Xml.XmlSerializer.dll

程序集:

System.Xml.dll

程序集:

netstandard.dll

获取或设置提供给序列化数组的 XML 元素名称。

public:
 property System::String ^ ElementName { System::String ^ get(); void set(System::String ^ value); };

public string ElementName { get; set; }

member this.ElementName : string with get, set

Public Property ElementName As String

属性值

String

序列化数组的 XML 元素名称。 默认值为向其分配 XmlArrayAttribute 的成员的名称。

示例

以下示例序列化类的 Library 实例，该实例包含一个名为 Books 返回项数组 Book 的属性。 该示例使用 ElementName 属性指定 XML 元素的数组应命名 My_Books 而不是 Books命名。

注解

指定 ElementName 何时希望生成的 XML 元素名称不同于成员的标识符。

只要生成的 XML 文档使用 XML 命名空间来区分相同命名的成员，就可以将相同的 ElementName 值设置为多个成员。 有关在 XML 文档中使用命名空间和创建前缀名称的更多详细信息，请参阅 XmlSerializerNamespaces。
