Question

我在将XML反序列化到位置列表对象时遇到问题给出以下XML：

<?xml version="1.0" encoding="utf-8"?>
    <locations>
        <location id="1">
            <level name="3" complete="True" stars="1" firstMisson="True" secondMission="False" thridMission="False" />
        </location>
        <location id="2">
           <level name="4" complete="True" stars="3" firstMisson="True" secondMission="True" thridMission="True" />
        </location>
    </locations>

以下课程：

    [System.Serializable]
    [XmlRoot(ElementName = "level")]
    public class Level
    {
        [XmlAttribute(AttributeName = "name")]
        public string Name { get; set; }
        [XmlAttribute(AttributeName = "complete")]
        public string Complete { get; set; }
        [XmlAttribute(AttributeName = "stars")]
        public string Stars { get; set; }
        [XmlAttribute(AttributeName = "firstMisson")]
        public string FirstMisson { get; set; }
        [XmlAttribute(AttributeName = "secondMission")]
        public string SecondMission { get; set; }
        [XmlAttribute(AttributeName = "thridMission")]
        public string ThridMission { get; set; }
    }
    [System.Serializable]
    [XmlRoot(ElementName = "location")]
    public class Location
    {
        [XmlElement(ElementName = "level")]
        public Level Level { get; set; }
        [XmlAttribute(AttributeName = "id")]
        public string Id { get; set; }
    }
    [System.Serializable]
    [XmlRoot(ElementName = "locations")]
    public class Locations
    {
        [XmlElement(ElementName = "location")]
        public Location Location { get; set; }

        public List<Locations> LocDb = new List<Locations>();
    }
    [System.Serializable]
    [XmlRoot(ElementName = "xml")]
    public class Xml
    {
        [XmlElement(ElementName = "locations")]
        public Locations Locations { get; set; }
    }

反序列化方法

     public List<Locations> locDB = new List<Locations>();

     public static void LoadData()
        {
            string filepath = Application.dataPath + @"/XML/GameXMLdata.xml";

            var xmlSerializer = new XmlSerializer(locDB.GetType());
            var stream = File.Open(filepath, FileMode.Open);


            locDB = (List<Locations>)xmlSerializer.Deserialize(stream);//locations xmlns=''> was not expected

            stream.Close();

            Debug.Log(locDB[1].Location.Id);

         }

那么如何将XML反序列化为位置对象列表？

非常感谢您的帮助。

您只需要两个课程：

[XmlType("level")]
public class Level
{
    [XmlAttribute("name")]
    public string Name { get; set; }
    [XmlAttribute("complete")]
    public string Complete { get; set; }
    [XmlAttribute("stars")]
    public string Stars { get; set; }
    [XmlAttribute("firstMisson")]
    public string FirstMisson { get; set; }
    [XmlAttribute("secondMission")]
    public string SecondMission { get; set; }
    [XmlAttribute("thridMission")]
    public string ThridMission { get; set; }
}

[XmlType("location")]
public class Location
{
    [XmlElement("level")]
    public Level Level { get; set; }
    [XmlAttribute("id")]
    public string Id { get; set; }
}

重要的是将XmlType属性应用于课程Location而不是XmlRoot。

现在，您可以将XML反序列化为List<Location>，如下所示：

var xmlSerializer = new XmlSerializer(typeof(List<Location>), 
    new XmlRootAttribute("locations"));
List<Location> locations;
using (var stream = File.OpenRead(filepath))
    locations = (List<Location>)xmlSerializer.Deserialize(stream);

诀窍是使用XmlSerializer(Type, XmlRootAttribute)构造函数重载指定根元素名称（在您的情况下为“locations”）。

Answer 2

我在类属性上遇到了类似的问题，并使用不同的方法解决了它。由于在我的场景中我无法触及 XmlSerializer 构造逻辑，这就是我所做的（使用来自 OP 的类型作为参考）：

[XmlRoot("locations")]
public sealed class LocationCollection : Collection<Location>
{
}

使用自定义集合类，我可以在设计时设置根目录并仍然使用标准的 XmlSeriaizer 实例。

不希望将Xml反序列化为List <t> - xmlns =''
