C#XML反序列化。从节点读取所有内部文本到字符串属性 [英] C# XML Deserialization. Read all inner text from node into string property
问题描述
我当前正在尝试修改类,以使模型上的text属性包含某个节点( text
)节点的所有内部文本。
I am currently trying to modify my classes so that a my text property on my model contains all inner text of a certain node (text
) node.
给我一些问题的xml示例是:
An example of the xml which is giving me issues is:
<component>
<section>
<title>Reason for Visit</title>
<text>
<content ID="ID3EZZKACA">No Reason for Visit was given.</content>
</text>
</section>
</component>
我的目标是模型的 text
属性
< content ID = ID0EAAKACA>未给出访问原因。< / content>
当前我的模型如下:
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,我目前正在尝试通过使用注释 [System.Xml.Serialization.XmlTextAttribute()]
完成此操作,
So, I am currently trying to accomplish this by using the annotation [System.Xml.Serialization.XmlTextAttribute()]
however when I do so, the text property is always coming through as null when the xml is deserialized.
推荐答案
正如我在评论中说的那样,以序列化通常更容易。对于上述XML,下面是一些类
As I said in a comment, starting with serialization is often easier. For the XML above, here are some classes
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 content 类修改为< a href = https://msdn.microsoft.com/zh-cn/library/83y7df3e(v=vs.110).aspx rel = nofollow noreferrer>控制XML序列化:
public sealed class content
{
[XmlText]
public string text { get; set; }
[XmlAttribute]
public string ID { get; set; }
}
然后可以使用以下代码序列化实例:
You can then serialize an instance with the following code:
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);
}
结果为以下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>
