注解

如果在应用特性时指定 Name 属性值，则插入到数组中的所有 XmlElement 或 XmlNode 对象必须具有相同的元素名称和默认命名空间，否则将引发异常。 如果设置 Namespace 属性值，还必须设置 Name 属性，并且 XmlElement 或 XmlNode 对象还必须具有相同的名称和命名空间值。 如果未指定任何 Name 值，则 XmlElement 或 XmlNode 对象可以具有任何元素名称。

调用 Deserialize 类的 XmlSerializer 方法时，所有在反序列化的对象中没有对应成员的属性都会收集到 数组中。 如果指定值 Name ，则数组仅包含具有该名称的 XML 元素。 如果未指定 Name 值，则数组包含类中没有相应成员的所有元素。 如果类包含多个应用了特性的字段，请使用 Name 和 Namespace 属性来区分数组的内容。 如果此类 (具有多个字段) 还包含一个没有设置 (的区分属性值的字段， Name 并且 Namespace) 反序列化期间，数组包含其他数组中尚未包含的任何 XML 元素。 如果添加的多个字段未设置区分 Name 或 Namespace 值，类中的最后一个字段将包含其他数组中尚未包含的所有未知元素，并且任何其他字段都设置为 null。

可以将 的 XmlAnyElementAttribute 多个实例应用于一个类成员，但每个实例必须具有不同的 Name 属性值。 或者，如果为每个实例设置了相同的 Name 属性，则必须为每个实例设置不同的 Namespace 属性值。
