C# XML 反序列化。将节点中的所有内部文本读入字符串属性

Question

我目前正在尝试修改我的类，以便我的模型上的文本属性包含某个节点 ( text) 节点的所有内部文本。

给我带来问题的 xml 示例是:

            <component>
                <section>
                    <title>Reason for Visit</title>
                    <text>
                        <content ID="ID3EZZKACA">No Reason for Visit was given.</content>
                    </text>
                </section>
            </component>

我的目标是我模型的 text属性具有以下字符串:

"<content ID="ID0EAAKACA">No Reason for Visit was given.</content>"

目前我的模型如下所示:

public partial class ComponentSection {
    //other model properties here
    private string textField;

    [System.Xml.Serialization.XmlTextAttribute()]
  public string text {
        get {
            return this.textField;
        }
        set {
            this.textField = value;
        }
    }
    //getters/setters for other properties here
}

因此，我目前正在尝试使用注释 [System.Xml.Serialization.XmlTextAttribute()] 来完成此操作但是，当我这样做时，当反序列化 xml 时，text 属性始终为 null。

正如我在评论中所说，从序列化开始通常更容易。对于上面的 XML，这里有一些类

public sealed class component
{
    public section section { get; set; }
}
public sealed class section
{
    public string title { get; set; }
    public text text { get; set; }
}
public sealed class text
{
    public content content { get; set; }
}
public sealed class content
{
    public string text { get; set; }
    public string ID { get; set; }
}

然后，将内容类修改为control XML serialization :

public sealed class content
{
    [XmlText]
    public string text { get; set; }
    [XmlAttribute]
    public string ID { get; set; }
}

然后您可以使用以下代码序列化一个实例:

        static string ToXmlString<T>(T t)
        {
            var serializer = new XmlSerializer(t.GetType());
            using (var sw = new System.IO.StringWriter())
            {
                serializer.Serialize(sw, t);
                return sw.ToString();
            }
        }
        static void Main(string[] args)
        {
            var c = new component { section = new section {
                            title = "Reason for Visit", text = new text { content = new content {
                            ID = "ID3EZZKACA", text = "No Reason for Visit was given." } } } };

            string s = ToXmlString(c);
            Console.WriteLine(s);
        }

结果是以下 XML:

<?xml version="1.0" encoding="utf-16"?>
<component xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http
://www.w3.org/2001/XMLSchema">
  <section>
    <title>Reason for Visit</title>
    <text>
      <content ID="ID3EZZKACA">No Reason for Visit was given.</content>
    </text>
  </section>
</component>
