我在我的 .Net 应用程序中使用第三方 Web 服务 [WS]。 我的应用程序正在使用从此 WS 的 wsdl 生成的实体类。 我从数据库中获取数据，将其填充到实体对象中，然后使用 XmlSerializer 类从中生成 xml。
WS 的方法之一需要此 xml 字符串作为输入。并且 xml 的元素顺序应与 WS 预期的顺序相同。但发生的情况是，某些元素在我的应用程序中出现颠倒，并且所以 WS 抛出一个最里面的异常，说关于序列化:。 _innerException {“顺序不一致:如果在类成员之一上使用，则所有类似粒子的成员都需要“顺序”属性，请在类成员上使用 XmlElement、XmlAnyElement 或 XmlArray 自定义属性显式设置“顺序”'仪器'。"} System.Exception {System.InvalidOperationException}
XmlSerializer serializer = new XmlSerializer(typeof(totemmessage));
所以，我的问题是，在将应用程序发送到 WS 之前，如何以编程方式控制应用程序中这些 xml 元素的顺序？注意:我不想为此目的使用 xslt。
感谢您的阅读。
这是我的实体类:

最佳答案
我在实体类中的每个属性之上使用了 XmlElement[Order =n]。因此，在尝试了排序之后，我可以使此序列化工作。继承和部分类使此修复变得更加困难!谢谢。
