C＃的Xml序列化列表＆LT; T＆GT;后代与XML属性 [英] C# Xml Serializing List<T> descendant with Xml Attribute

问题描述

早晨家伙，

我从名单下降，具有公共属性的集合。 XML序列化不拿起我的广告载体。列表项序列罚款。我曾尝试XmlAttribute属性无济于事。难道你们有一个解决方案？

 公共部分类主窗口：窗口
{
    公共主窗口（）
    {
        的InitializeComponent（）;
    }
    私人无效的button1_Click（对象发件人，RoutedEventArgs E）
    {
        变种人=新PersonCollection
        {
            新的Person {名字=苏，年龄= 17}，
            新的Person {名字=乔，年龄= 21}
        };
        people.FavoritePerson =苏;        变种X =新的XmlSerializer（people.GetType（））;
        变种B =新的StringBuilder（）;
        变种W = XmlTextWriter.Create（B，新XmlWriterSettings {NewLineChars =\\ r \\ n，缩进=真}）;
        x.Serialize（W，人）;
        变种S = b.ToString（）;
    }
}[XmlRoot（的ElementName =人物）
公共类PersonCollection：列表＆LT;＆人GT;
{
    //不行！ ARGHHH
    [XmlAttribute]
    公共字符串FavoritePerson {搞定;组; }
}公共类Person
{
    [XmlAttribute]
    公共字符串名字{获得;组; }
    [XmlAttribute]
    公众诠释年龄{搞定;组; }
}
 

我得到下面的XML

 ＆LT;？XML版本=1.0编码=UTF-16＆GT？;
        ＆LT;人的xmlns：XSI =htt​​p://www.w3.org/2001/XMLSchema-instance的xmlns：XSD =htt​​p://www.w3.org/2001/XMLSchema＆GT;
          ＆LT;人姓=苏年龄=17/＆GT;
          ＆LT;人姓=乔年龄=21/＆GT;
        ＆LT; /人＆GT;
 

我想获得这个

 ＆LT;？XML版本=1.0编码=UTF-16＆GT？;
        ＆LT;人民FavoritePerson =苏的xmlns：XSI =htt​​p://www.w3.org/2001/XMLSchema-instance的xmlns：XSD =htt​​p://www.w3.org/2001/XMLSchema＆GT;
          ＆LT;人姓=苏年龄=17/＆GT;
          ＆LT;人姓=乔年龄=21/＆GT;
        ＆LT; /人＆GT;
 

解决方案

这是不是一个问题的答案，但我想我会做一个建议，在code开发，以缓解。

添加一个新的添加方法的 PersonCollection 类，例如：

 公共类PersonCollection：列表＆LT;人＆gt;中的IXmlSerializable
{
...
    公共无效添加（串名字，年龄INT）
    {
        this.Add（新的Person（名字，年龄））;
    }
...
}
 

然后，通过这样做，可以简化您的集合初始化语法：

 变种人=新PersonCollection
{
    {苏，17}，
    {乔，21}
};
people.FavoritePerson =苏;
 

Morning Guys,

I have a collection that descends from List and has a public property. The Xml serializer does not pick up my proeprty. The list items serialize fine. I have tried the XmlAttribute attribute to no avail. Do you guys have a solution?

    public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();
    }
    private void button1_Click(object sender, RoutedEventArgs e)
    {
        var people = new PersonCollection
        {
            new Person { FirstName="Sue", Age=17 },
            new Person { FirstName="Joe", Age=21 }
        };
        people.FavoritePerson = "Sue";

        var x = new XmlSerializer(people.GetType());
        var b = new StringBuilder();
        var w = XmlTextWriter.Create(b, new XmlWriterSettings { NewLineChars = "\r\n", Indent = true });
        x.Serialize(w, people);
        var s = b.ToString();
    }
}

[XmlRoot(ElementName="People")]
public class PersonCollection : List<Person>
{
    //DOES NOT WORK! ARGHHH
    [XmlAttribute]
    public string FavoritePerson { get; set; }    
}

public class Person
{
    [XmlAttribute]
    public string FirstName { get; set; }
    [XmlAttribute]
    public int Age { get; set; }
}

I'm getting the following xml

<?xml version="1.0" encoding="utf-16"?>
        <People xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
          <Person FirstName="Sue" Age="17" />
          <Person FirstName="Joe" Age="21" />
        </People>

I would like to get this

<?xml version="1.0" encoding="utf-16"?>
        <People FavoritePerson="Sue" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
          <Person FirstName="Sue" Age="17" />
          <Person FirstName="Joe" Age="21" />
        </People>

解决方案

This isn't an answer to the question, but I thought I'd make a suggestion to ease in code development.

Add a new Add method to the PersonCollection class as such:

public class PersonCollection : List<Person>, IXmlSerializable
{
...
    public void Add(string firstName, int age)
    {
        this.Add(new Person(firstName, age));
    }
...
}

Then, by doing this, you can simplify your collection initializer syntax to:

var people = new PersonCollection
{
    { "Sue", 17 },
    { "Joe", 21 }
};
people.FavoritePerson = "Sue";
