C# XmlAnyElementAttribute：如何将项目添加到列表<；System.Xml.xmlement>；对于XSD<；任何>；xsd2code创建的类中的元素？

我使用XSD2代码来创建C#类，它可以基于一组XSD文件序列化/反序列化XML文件

一个XSD文件包含一个

）
实现这一点的唯一方法是一个非常麻烦的方法。首先，在对象中创建所需的结构。序列化该对象并将其用作新XmlDocument的输入，然后将DocumentElement添加到any elementlist

下面是一个可以帮助您的小示例

msg.xsd

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns="http://tempuri.org/msg" xmlns:type="http://tempuri.org/type" targetNamespace="http://tempuri.org/msg" elementFormDefault="qualified" attributeFormDefault="unqualified">
    <xs:import namespace="http://tempuri.org/type" schemaLocation="type.xsd"/>
    <xs:element name="ExampleMsg">
        <xs:complexType>
            <xs:sequence>
                <xs:element name="Parent">
                    <xs:complexType>
                        <xs:sequence>
                            <xs:element name="Child1" type="xs:string"/>
                            <xs:element name="Child2" type="type:AnyType"/>
                        </xs:sequence>
                    </xs:complexType>
                </xs:element>
            </xs:sequence>
        </xs:complexType>
    </xs:element>
</xs:schema>

守则：

static void Main(string[] args)
        {
            var msg = new ExampleMsg {Parent = new ExampleMsgParent {Child1 = "Rob"}};

            var mike = new Mike {Age = 1};
            var john = new John {Age = 2};
            var nick = new Nick {Age = 3};

            var xdoc = new XmlDocument();
            
            xdoc.LoadXml(mike.Serial());
            msg.Parent.Child2.Any.Add(xdoc.DocumentElement);

            xdoc.LoadXml(john.Serial());
            msg.Parent.Child2.Any.Add(xdoc.DocumentElement);

            xdoc.LoadXml(nick.Serial());
            msg.Parent.Child2.Any.Add(xdoc.DocumentElement);

            var msgstring = msg.Serial();
            Console.WriteLine(msgstring);

            Console.ReadLine();
        }

以及输出：

<?xml version="1.0" encoding="utf-8"?>
<ExampleMsg xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://tempuri.org/msg">
    <Parent>
        <Child1>Rob</Child1>
        <Child2>
            <Mike xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://tempuri.org/type">
                <Age>1</Age>
            </Mike>
            <John xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://tempuri.org/type">
                <Age>2</Age>
            </John>
            <Nick xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://tempuri.org/type">
                <Age>3</Age>
            </Nick>
        </Child2>
    </Parent>
</ExampleMsg>

XmlAnyElement can only be used with classes of type XmlNode or a type deriving from XmlNode

[XmlArrayItemAttribute("AnyPlugInContainerType"Namespace = "http://www.extra-standard.de/namespace/plugins/1", Order = 0)]
public List<AbstractPlugInType> Any
{
  get { return _any; }
  set { _any = value; }
}
