如何反序列化XML数组项

本文关键字：数组 XML 反序列化 | 更新日期: 2023-09-27 18:06:32

我在反序列化XML时有问题。我得到AccountInformation工作，但它不会与联盟元素工作。XML不包含任何"Leauges"的标记，我不想添加该标记以使其工作。还有其他的方法来"修复"它吗?我尝试了不同的解决方案，但联赛的反序列化结果是空的。我错过了什么?

感谢任何帮助!

查看下面的代码:

我已经修改了代码和XML，但我不会工作。我遗漏了什么?

[Serializable]
[XmlRoot(ElementName = "LeaugeCollection", Namespace = "")]
public class LeagueCollection
{
    [XmlArray("Leagues")]
    [XmlArrayItem("League",typeof(League))]
    public  League[] League { get; set; }
    [XmlElement(ElementName = "AccountInformation")]
    public string AccountInformation { get; set; }
}
[Serializable()]
public class League
{
    [XmlElement(ElementName = "Id")]
    public int Id { get; set; }
    [XmlElement(ElementName = "Name")]
    public string Name { get; set; }
    [XmlElement(ElementName = "Country")]
    public string Country { get; set; }
    [XmlElement(ElementName = "Historical_Data")]
    public string Historical_Data { get; set; }
    [XmlElement(ElementName = "Fixtures")]
    public string Fixtures { get; set; }
    [XmlElement(ElementName = "LiveScore")]
    public string Livescore { get; set; }
    [XmlElement(ElementName = "NumberOfMatches")]
    public int NumberOfMatches { get; set; }
    [XmlElement(ElementName = "LatestMatch")]
    public DateTime LatestMatch { get; set; }
}

反序列化代码:

public static void Main(string[] args)
    {
        XmlSerializer deserializer = new XmlSerializer(typeof(LeagueCollection));
        TextReader reader = new StreamReader(@"C:'XmlFiles'XmlSoccer.xml");
        object obj = deserializer.Deserialize(reader);
        LeagueCollection XmlData = (LeagueCollection)obj;
        reader.Close();
    }

提前感谢!

如何反序列化XML数组项

您在图像中的XML缺少实际的数组元素(Leauges)，它只有数组项元素(Leauge)，这就是为什么您无法将其反序列化!

更新:复制一下你的代码，我看到XML中元素的拼写是"League"而在你的代码中是"League"

先修复!

更新2:在你根据我的评论做了编辑之后，它似乎工作得很好!

您缺少一个名称空间。我不喜欢联盟和联盟。联盟是不必要的。
