如何反序列化 XML 數組項？

Question

我在反序列化 XML 時遇到問題。 我讓 AccountInformation 工作，但它不適用於 Leauge 元素。 XML 不包含任何“Leauges”標簽，我不想添加該標簽以使其正常工作。 有沒有其他方法可以“修復”它？ 我嘗試了不同的解決方案，但 leauges 的反序列化結果返回空。 我錯過了什么？

任何幫助表示贊賞！

下面是我的代碼：

更新：

我已經修改了代碼和 XML，但無論如何我都不會工作。 我在這里缺少什么？

[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; }
}

反序列化代碼：

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();
    }

鏈接到 XML：

提前致謝！

Answer 1

您在圖像中擁有的 XML 缺少實際的數組元素 (Leauges)，它只有數組項元素 (Leauge)，這就是您無法對其進行反序列化的原因！

更新：好的，嘗試重現您的代碼，我現在看到在您的 XML 中，您的元素拼寫為“League”，而在您的代碼“Leauge”中

先解決這個問題！

UPDATE2：根據我的評論進行編輯后，它似乎工作正常！

Answer 2

您缺少命名空間。 我不喜歡聯賽和聯賽。 聯賽是不必要的。
