以编程方式控制 xml 元素的顺序

Question

我在我的 .Net 应用程序中使用第三方网络服务 [WS]。 我的应用程序正在使用从这个 WS 的 wsdl 生成的实体类。 我从 db 中获取数据，将其填充到实体对象中，然后使用 XmlSerializer 类从中生成一个 xml。

WS 的其中一种方法需要此 xml 字符串作为输入。并且 xml 应该具有与 WS 预期的顺序相同的元素。但是发生的事情是一些元素在我的应用程序中颠倒了，并且所以 WS 在序列化上抛出了一个最里面的异常：。 _innerException {“不一致的顺序：如果用于类的成员之一，所有类粒子成员都需要'Order'属性，请使用类成员的XmlElement，XmlAnyElement或XmlArray自定义属性显式设置'Order''仪器'。"} System.Exception {System.InvalidOperationException}

XmlSerializer serializer = new XmlSerializer(typeof(totemmessage));

所以，我的问题是，在将这些 xml 元素发送到 WS 之前，如何以编程方式控制这些 xml 元素在我的应用程序中的顺序？注意：我不想为此目的使用 xslt。

感谢阅读。

这是我的实体类：

Answer 1

我在实体类中的每个属性之上使用了 XmlElement[Order =n]。所以，在玩弄了排序之后，我可以使这个序列化工作。继承和部分类使这个修复变得更加困难！谢谢。

Answer 2

XmlSerializer 按类中的声明顺序生成元素 - 你能改变实体中的顺序吗？

如何将Order = N 与其他 XML 属性和 List 集合一起使用。

public class MyClass
{
   [XmlAnyElement("My-XLMComment", Order = 3)] public XmlComment CommentA { get; set; } = new XmlDocument().CreateComment("This is an XML comment");
   [XmlAttribute("MyAttribute")] public string str4 { get; set; } //This is a XML-Attribute, Order not applicable
   [XmlIgnore] public string str1 { get; set; } //This is a [XmlIgnore], Order not applicable
   [XmlElement(Order = 5)] public string str2 { get; set; } // Standard property with Order    
   [XmlElement(Order = 2)] public string str3 { get; set; } // Standard property with Order    
   [XmlElement(Order = 1)] public List<MyList> ListElms = new List<MyList> //List collection with Order
   {
      new ListElm {str1 = "xxx", str2 ="yyy", str3 ="zzz"} ,
      new ListElm {str1 = "xxx", str2 ="yyy", str3 ="zzz"}
   };

   public class MyList
   {
      [XmlElement(Order = 3)] public string str1 { get; set; } // Order can be assigned, but not mandatory 
      [XmlElement(Order = 2)] public string str2 { get; set; } // Order can be assigned, but not mandatory
      [XmlElement(Order = 1)] public string str3 { get; set; } // Order can be assigned, but not mandatory
   }
}

将序列化为：

<MyClass MyAttribute="str4">
    <ListElms>
       <str3>zzz</str3>
       <str2>yyy</str2>
       <str1>xxx</str1>
    </ListElms>
    <ListElms>
       <str3>zzz</str3>
       <str2>yyy</str2>
       <str1>xxx</str1>
    </ListElms>
       <str3>str3</str3>
       <!--This is an XML comment-->
       <str2>str2</str2>
</MyClass>
