Question

这是我输入的XML文件：

<?xml version="1.0" encoding="UTF-8"?>
<hosts>
  <host>
    <hostId>239|BS|OWN</hostId>
    <images>
      <image>
        <name>Pic.jpg</name>
        <main>true</main>
        <source>../Images/Melissa/Pic.jpg</source>
      </image>
    </images>
  </host>
</hosts>

这是我用来解除XML文件的类：

[XmlRoot("hosts")]
public class hosts
{
    [XmlElement("host")]       
    public List<Host> Listehosts { get; set; }
}


public class Host
{
    [XmlElement("hostId")]
    public string hostId { get; set; }              

    [XmlElement("images")]
    public List<Image> Listeimages { get; set; }
}


public class Image
{
    [XmlElement("name")]
    public string name { get; set; }
    [XmlElement("main")]
    public string main { get; set; }
    [XmlElement("source")]
    public string source { get; set; }      
}

这是我主程序的代码：

string outputTmp = "Images.xml";
XmlSerializer deserializer = new XmlSerializer(typeof(hosts));
TextReader reader = new StreamReader(outputTmp);
object obj = deserializer.Deserialize(reader);
hosts XmlData = (hosts)obj;
reader.Close();            
Console.WriteLine(XmlData.Listehosts.Count);

问题是当我执行程序时，图像列表总是空的。主机列表已正确收费但当我检查图片列表时，它包含所有属性（name，main，source）的永久空值。

我错过了什么吗？

Answer 1

试试这个：

    public class Host
    {
         [XmlElement("hostId")]
         public string hostId { get; set; }              

         [XmlArray("images")] // CHANGED
         [XmlArrayItem("image", typeof(Image))] // CHANGED
         public List<Image> Listeimages { get; set; }
    }

Answer 2

您的代码中存在一个小错误，添加一个带有列表的ImageCollection类。

public class ImageCollection
{
    [XmlElement("image")]  
    public List<Image> Listeimages { get; set; }
}

public class Host
{
     [XmlElement("hostId")]
     public string hostId { get; set; }              

     [XmlElement("images")]
     public ImageCollection ImageCollection { get; set; }
}
