XML反序列化内部异常

Question

我正在尝试将XML文件反序列化为一个类。XML文件如下所示：

<?xml version="1.0" encoding="utf-8"?>
<locations>
<location id="0">
    <name>park</name>
    <temperature>5</temperature>
    <wind>26</wind>
    <weather_text_SI>sunny</weather_text_SI>
    <visibility></visibility>
    <latitude>46.4527</latitude>
    <longitude>15.334</longitude>
    <elevation>1517</elevation>
</location>
</locations>

我想要将其反序列化的类是：

[XmlRootAttribute("locations")]
public class SnowPark
{
    public SnowPark()
    {
    }

    private int id;
    [XmlAttribute("id")] 
    public int Id
    {
        get { return id; }
        set { id = value; }
    }

    private string name;
    [XmlElement("name")]
    public string Name
    {
        get { return name; }
        set { name = value; }
    }

    private int temperature;
    [XmlElement("temperature")]
    public int Temperature
    {
        get { return temperature; }
        set { temperature = value; }
    }

    private int wind;
    [XmlElement("wind")]
    public int Wind
    {
        get { return wind; }
        set { wind = value; }
    }

    private string weatherText;
    [XmlElement("weather_text_SI")]
    public string WeatherText
    {
        get { return weatherText; }
        set { weatherText = value; }
    }

    private double latitude;
    [XmlElement("latitude")]
    public double Latitude
    {
        get { return latitude; }
        set { latitude = value; }
    }

    private double longitude;
    [XmlElement("longitude")]
    public double Longitude
    {
        get { return longitude; }
        set { longitude = value; }
    }

    private int elevation;
    [XmlElement("elevation")]
    public int Elevation
    {
        get { return elevation; }
        set { elevation = value; }
    }
}

我尝试反序列化XML文件。

XmlSerializer deserializer = new XmlSerializer(typeof(List<SnowPark>));
TextReader textReader = new StreamReader(@"file.xml");
List<SnowPark> parks;
parkss = (List<SnowPark>)deserializer.Deserialize(textReader);
textReader.Close();

然而，我得到了一个异常：

There is an error in XML document (2, 2).

和一个内部异常：

<locations xmlns=''> was not expected.

到目前为止还没有找到解决方案。感谢你的帮助。

Answer 1

XmlRootAttribute不适用，因为您序列化的是then的列表，而不是单个条目；这也意味着您的XML比所需的要更深一层。

IMO，您在这里最简单的选择是：

[XmlRoot("locations")]
public class Locations
{
    [XmlElement("location")]
    public List<SnowPark> Parks {get;set;}
}

并反序列化Locations对象，使用typeof(Locations)初始化XmlSerializer
