【问题标题】:XML to LINQ deserialize to an object from an XML DocumentXML to LINQ 反序列化为 XML 文档中的对象

【问题描述】:

好吧,这些命名空间又让我头疼了。

我想获取一个长 XML 文档并将其反序列化为实体对象列表。本例中的对象类似于平面 POJO。

XML 看起来像:

<Envelope xmlns="http://schemas.xmlsoap.org/soap/envelope/">
  <Body>
    <QueryResponse xmlns="http://markets.midwestiso.org/dart/xml">
      <DayAheadLMP day="2011-02-25">
        <PricingNode location="AEC">
          <PricingNodeHourly hour="1">
            <LMP>23.1</LMP>
            <MCC>-0.44</MCC>
            <MLC>-0.49</MLC>
            <RegMCP>0</RegMCP>
            <SpinMCP>0</SpinMCP>
            <SuppMCP>0</SuppMCP>
          </PricingNodeHourly>

等等等等。

我已经做到了:

var repsonseXML = XDocument.Parse(CallMUI(requestXml, muiUrl));

它将我的 XML 作为字符串返回并将其解析为 XDocument 对象

我想要的列表对象如下:

    /// <summary>
/// There are no comments for MISO.IR.IntegrationModel.LMP_DayAhead in the schema.
/// </summary>
/// <KeyProperties>
/// Location
/// Interval
/// SyncId
/// </KeyProperties>
[global::System.Data.Objects.DataClasses.EdmEntityTypeAttribute(NamespaceName="MISO.IR.IntegrationModel", Name="LMP_DayAhead")]
[global::System.Runtime.Serialization.DataContractAttribute(IsReference=true)]
[global::System.Serializable()]
public partial class LMP_DayAhead : global::System.Data.Objects.DataClasses.EntityObject
{
    /// <summary>
    /// Create a new LMP_DayAhead object.
    /// </summary>
    /// <param name="location">Initial value of Location.</param>
    /// <param name="interval">Initial value of Interval.</param>
    /// <param name="lMP">Initial value of LMP.</param>
    /// <param name="mLC">Initial value of MLC.</param>
    /// <param name="mCC">Initial value of MCC.</param>
    /// <param name="syncId">Initial value of SyncId.</param>
    [global::System.CodeDom.Compiler.GeneratedCode("System.Data.Entity.Design.EntityClassGenerator", "4.0.0.0")]
    public static LMP_DayAhead CreateLMP_DayAhead(string location, global::System.DateTime interval, decimal lMP, decimal mLC, decimal mCC, int syncId)
    {
        LMP_DayAhead lMP_DayAhead = new LMP_DayAhead();
        lMP_DayAhead.Location = location;
        lMP_DayAhead.Interval = interval;
        lMP_DayAhead.LMP = lMP;
        lMP_DayAhead.MLC = mLC;
        lMP_DayAhead.MCC = mCC;
        lMP_DayAhead.SyncId = syncId;
        return lMP_DayAhead;
    }

如何使用所有这些命名空间来完成它?

【解决方案1】:

您将要查看 System.Xml.Serialization 命名空间。

LMP_DayAhead dayAhead = GetDayAheadData();
var serializer = new XmlSerializer(dayAhead.GetType());
using (var writer = XmlWriter.Create("dayahead.xml"))
{
    serializer.Serialize(writer, shoppingCart);
}

就命名空间而言,您的 poco 将不得不模仿 xml 中的继承,我相信有一种方法可以告诉序列化程序忽略命名空间(我不记得了)

    【解决方案2】:

    我想我明白了:

    public static void ProcessDayAheadQuery(string requestXml, int syncEntityId, string muiUrl)
    {
        var repsonseXML = XDocument.Load(XmlReader.Create(CallMUIStream(requestXml, muiUrl)));
        XNamespace ns = "http://schemas.xmlsoap.org/soap/envelope/";
        XNamespace ns2 = "http://markets.midwestiso.org/dart/xml";
    
        using (var db = new IntLMPDB())
        {
            SyncJob syncEntity =
                (from s in db.SyncJob where s.SyncId == syncEntityId select s).FirstOrDefault();
            DateTime rDay = DateTime.Now;
            String query = String.Empty;
    
            foreach (XElement xe in repsonseXML.Descendants(ns + "Envelope").FirstOrDefault().Descendants(ns2 + "QueryResponse").Descendants(ns2 + "DayAheadLMP"))
            {
                rDay = DateTime.Parse(xe.FirstAttribute.Value);
                query = xe.Name.LocalName;
                // string day = xe.FirstAttribute.Value;
                foreach (XElement node in xe.Descendants(ns2 + "PricingNode"))
                {
                   // string location = node.FirstAttribute.Value;
                    strin
                    foreach (XElement hourly in node.Descendants(ns2 + "PricingNodeHourly"))
                    {
                        //var newRow = new LMP_DayAhead
                        //{
                        //    Location = node.FirstAttribute.Value,
                        //    Interval = rDay.AddHours(Double.Parse(hourly.FirstAttribute.Value)),
                        //    LMP = decimal.Parse(hourly.Descendants(ns2 + "LMP").FirstOrDefault().Value),
                        //    MLC = decimal.Parse(hourly.Descendants(ns2 + "MLC").FirstOrDefault().Value),
                        //    MCC = decimal.Parse(hourly.Descendants(ns2 + "MCC").FirstOrDefault().Value),
                        //    SyncJob = syncEntity
                        //};
                        //db.AddToLMP_DayAhead(newRow);     
                    }
                }
    
            }
            db.SaveChanges();
            UpdateLastDbPost(db, query, rDay);
        } 
    }
