注解

该 MessagePart 类对应于 Web 服务描述语言 (WSDL) <part> 元素括起来的 <message> 元素，该元素又由 <definitions> 根元素括起来。有关 WSDL 的更多信息，请参阅 WSDL 规范。

属性

Capacity	获取或设置 CollectionBase 可包含的元素数。 (继承自 CollectionBase)
Count	获取 CollectionBase 实例中包含的元素数。不能重写此属性。 (继承自 CollectionBase)
InnerList	获取一个 ArrayList，它包含 CollectionBase 实例中元素的列表。 (继承自 CollectionBase)
Item[Int32]	获取或设置位于指定的从零开始的索引处的 MessagePart 值。
Item[String]	获取由其名称指定的 MessagePart。
List	获取一个 IList，它包含 CollectionBase 实例中元素的列表。 (继承自 CollectionBase)
