c# - 反序列化 XML 元素数组

Question

所以，反序列化正在工作，但是我有一些这样的 xml:

<File>
  <Stuff>stuff</Stuff>
  <Devices>
    <Device Type="1">
      <Number>1</Number>
    </Device>
    <Device Type="2">
      <Number>2</Number>
    </Device>
  </Devices>
</File>

当它到达设备数组时...第一个设备是唯一填充到对象中的设备。以下是类(class):

            XmlSerializer deserializer;
            XmlRootAttribute xRoot = new XmlRootAttribute();
            FileStream stream = new FileStream(CONFIG_PATH, FileMode.Open);
            XmlReader reader = new XmlTextReader(stream);

            // Details configuration area.
            xRoot.ElementName = "File";
            xRoot.IsNullable = true;
            deserializer = new XmlSerializer(typeof(File), xRoot);
            Configuration = (File)deserializer.Deserialize(reader);

[Serializable()]
[XmlRoot(ElementName = "File", IsNullable = true)]
public sealed class File
{
    [XmlElement("Devices")]
    public Devices Devices { get; set; }
}

// <summary>
/// Configuration device elements.
/// </summary>
[Serializable()]
[XmlRoot("Devices", IsNullable = true)]
public sealed class Devices
{
    [XmlElement("Device")]
    public DeviceElements[] DeviceElements { get; set; }
}

/// <summary>
/// Configuration Devices.
/// </summary>
[Serializable()]
[XmlRoot("Device", IsNullable = true)]
public sealed class DeviceElements
{
    [XmlAttribute("Type")]
    public string DeviceType { get; set; }

    [XmlElement("Number")]
    public int DeviceNumber { get; set; }
}

同样，只有第一个 Device 被填充，我玩过 XmlArray 和 XmlArrayItem 但是它们都没有给我第一个值。有什么建议吗？

你一定是在别的地方做错了什么。仅使用 XML 的 Devices 部分:

  <Devices>
    <Device Type="1">
      <Number>1</Number>
    </Device>
    <Device Type="2">
      <Number>2</Number>
    </Device>
  </Devices>

我能够成功反序列化具有多个 DeviceElements 子级的 Devices 类实例，使用与您在上一个问题中使用的类似代码给出您上面的类:

FileStream stream = new FileStream("test.xml", FileMode.Open);
XmlReader reader = new XmlTextReader(stream);

XmlSerializer deserializer = new XmlSerializer(typeof(Devices));
var devicesResult = (Devices)deserializer.Deserialize(reader);

编辑:

使用完整的 XML:

<File>
  <Stuff>stuff</Stuff>
  <Devices>
    <Device Type="1">
      <Number>1</Number>
    </Device>
    <Device Type="2">
      <Number>2</Number>
    </Device>
  </Devices>
</File>

这对我来说成功反序列化了:

FileStream stream = new FileStream("test.xml", FileMode.Open);
XmlReader reader = new XmlTextReader(stream);

XmlRootAttribute xRoot = new XmlRootAttribute();
xRoot.ElementName = "File";
xRoot.IsNullable = true;

XmlSerializer deserializer = new XmlSerializer(typeof(File), xRoot);
var fileResult = (File)deserializer.Deserialize(reader);

附带说明 - 您可能不应该将您的类命名为与 .NET 框架中已有的类相同的名称 (System.IO.File)，同样在上面的代码示例中设置 Xml 根不需要，因为您无论如何都使用相同的名称，只需将其省略即可:

FileStream stream = new FileStream("test.xml", FileMode.Open);
XmlReader reader = new XmlTextReader(stream);
XmlSerializer deserializer = new XmlSerializer(typeof(File));
var fileResult = (File)deserializer.Deserialize(reader);
