C# 使用DataContractSerializer反序列化WCF中的XML

我正在向WCF REST服务发布一个XML文档。我能够使用DataContractSerializer获取要解析的元素，但无法提取属性。我尝试了其他SO问题的几种方法，但要么无法获得要解析的属性，要么无法生成正确的对象。例如，我的代码目前只解析一个字段数据，字段列表为空。提供的代码是我的最新尝试

我在我的MLW类上实现了IXmlSerializable，并且能够解析出属性，但是我在孩子们身上遇到了麻烦。因为我使用的是XMlReader，所以我得到了意想不到的结果，因为子类中的读取器对于它们在文档中的位置没有任何上下文。其他示例只显示了容器元素中可以解析为列表的一种数据类型，但我有几个FieldData元素，它们是Job元素的同级

有没有更好的方法来实现这一点

这是我的MLW课程

[XmlRoot(ElementName = "MLW", Namespace = "")]
public class MLW : IXmlSerializable
{
    public string Cmd { get; set; }
    public string OrgId { get; set; }
    public string Id { get; set; }
    public string LTStamp { get; set; }
    public string TStamp { get; set; }
    public string DevId { get; set; }
    public string RouteId { get; set; }
    public string TruckId { get; set; }
    public string SType { get; set; }
    public string LocationAddress { get; set; }
    public string LocationCity { get; set; }
    public string LocationState { get; set; }
    public string LocationPostalCode { get; set; }
    public string StopId { get; set; }
    public string LocationKey { get; set; }

    public List<FieldData> FieldDatas = new List<FieldData>();

    public XmlSchema GetSchema()
    {
        return null;
    }

    public void ReadXml(XmlReader reader)
    {
        XmlSerializer serializer = new XmlSerializer(typeof(FieldData));

        Cmd = reader.GetAttribute("Cmd");
        OrgId = reader.GetAttribute("OrgId");
        Id = reader.GetAttribute("Id");
        LTStamp = reader.GetAttribute("LTStamp");
        TStamp = reader.GetAttribute("TStamp");
        DevId = reader.GetAttribute("DevId");
        RouteId = reader.GetAttribute("RouteId");
        TruckId = reader.GetAttribute("TruckId");
        SType = reader.GetAttribute("SType");
        LocationAddress = reader.GetAttribute("LocationAddress");
        LocationCity = reader.GetAttribute("LocationCity");
        LocationState = reader.GetAttribute("LocationState");
        LocationPostalCode = reader.GetAttribute("LocationPostalCode");
        StopId = reader.GetAttribute("StopId");
        LocationKey = reader.GetAttribute("LocationKey");

        while (reader.Read())
        {
            if (reader.IsStartElement())
            {
                switch (reader.Name.ToString())
                {
                    case "FieldData":
                        FieldDatas.Add((FieldData)serializer.Deserialize(reader));
                        break;
                }
            }
        }
    }

    public void WriteXml(XmlWriter writer){ }
}

这就是XML

更新

我可以通过向服务接口中的端点定义添加[XmlSerializerFormat]并使用Visual Studio的“将XML粘贴为类”功能为您构建XML所需的类来实现它

您应该尝试将属性显式标记为元素或属性

如

看起来你做的事情比这里需要的还要多。（我这样说是因为我不知道你项目的大背景）

---

您应该能够创建一些POCO，让datacontract序列化程序完成它的工作。只需根据需要使用[XmlRoot]、[XmlElement]、[XmlAttribute]和[XmlArray]来提示序列化程序。我通常不会处理所有这些readxml方法，因为这基本上相当于手动反序列化，这并没有真正节省我任何时间。

我会将此标记为答案，但我还必须做一些其他事情。

public class Field : IXmlSerializable
{
    public string FId { get; set; }

    public XmlSchema GetSchema()
    {
        return null;
    }

    public void ReadXml(XmlReader reader)
    {
        FId = reader.GetAttribute("FId");
    }

    public void WriteXml(XmlWriter writer) { }
}
