从 XSD 创建的 类 的反序列化不包含所有数据
Deserialization to classes created from XSD does not contain all data
我想将包含运动数据的 TCX 文件反序列化到我的 local/temporary 对象中。我使用了 XSD schema describing 这样的格式，并使用 xsd2code 创建了 类。
之后，我能够将 XML 反序列化为正确的对象，并且反序列化器没有抛出任何异常。但是当我开始扩展组件的行为时，我注意到有些字段不是正确的全字段。
问题是关于读取标签曲目。子结构中的反序列化 Lap 正确显示所有数据，但 Tracks 编号显示为 0。
有什么方法可以触发解串器来正确解释它吗？我错过了一些属性吗？为什么没有异常也读不准
我知道，很难解释并将所有需要的 类 放入评论中 - 所以我分享我的 current status here 并写下：GetUnifiedData_WhenTrackPointsAreGivenInTcx_UnifiedTrackPointShouldRetreiveIt() 没有通过并且显示我的问题。

问题是你的数据模型不对。在下面的摘录中，您将在 Lap 元素下方看到两个 Track 元素：
<?xml version="1.0" encoding="utf-16" standalone="no"?>
<TrainingCenterDatabase xmlns="http://www.garmin.com/xmlschemas/TrainingCenterDatabase/v2" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.garmin.com/xmlschemas/ActivityExtension/v2 http://www.garmin.com/xmlschemas/ActivityExtensionv2.xsd http://www.garmin.com/xmlschemas/FatCalories/v1 http://www.garmin.com/xmlschemas/fatcalorieextensionv1.xsd http://www.garmin.com/xmlschemas/TrainingCenterDatabase/v2 http://www.garmin.com/xmlschemas/TrainingCenterDatabasev2.xsd">

</Trackpoint>
<Trackpoint>

<Track>

<Trackpoint>

但是，在您的数据模型中，Track 是 Lap 的单例 属性，包含 TrackPoint_t 个条目的数组。当 XmlSerializer 遇到多个 Track 元素时，它无法反序列化它们。
因此您的数据模型需要如下所示。介绍一个中间人 class Track_t:
[System.Xml.Serialization.XmlTypeAttribute(Namespace = "http://www.garmin.com/xmlschemas/TrainingCenterDatabase/v2")]
public class Track_t
{
public Track_t()
{
this.Track = new List<Trackpoint_t>();
}
[System.Xml.Serialization.XmlElement("TrackPoint", typeof(Trackpoint_t), IsNullable = false)]
public List<Trackpoint_t> Track { get; set; }
}
并修改ActivityLap_t如下：
[System.CodeDom.Compiler.GeneratedCodeAttribute("System.Xml", "4.0.30319.34234")]
[System.SerializableAttribute()]
[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")]
[System.Xml.Serialization.XmlTypeAttribute(Namespace = "http://www.garmin.com/xmlschemas/TrainingCenterDatabase/v2")
]
public partial class ActivityLap_t
{
private List<Track_t> _track; // Change type to `Track_t`
public ActivityLap_t()
{
this._extensions = new Extensions_t();
this._track = new List<Track_t>(); // Change type to `Track_t`
this._maximumHeartRateBpm = new HeartRateInBeatsPerMinute_t();
this._averageHeartRateBpm = new HeartRateInBeatsPerMinute_t();
}
// Change type to `Track_t` and change attribute to `XmlElement`
[System.Xml.Serialization.XmlElement("Track", typeof(Track_t), IsNullable = false)]
public List<Track_t> Track
{
get { return this._track; }
set { this._track = value; }
}
// Remainder unchanged.
}
您还需要以同样的方式修改Course_t。
xsd 确实指定了类型 Track_t 的存在，并且 ActivityLap_t 可以包含无限数量的 Track 这种类型的元素，所以不知何故 XSD 被错误地转换为 classes:
<xsd:complexType name="ActivityLap_t">
