c# - 将xml反序列化为c#对象

Question

我有以下 xml(我无法编辑):

<?xml version="1.0" encoding="UTF-8"?>

<ns0:prices xmlns:ns0="http://schemas.some.com/sadas/Output">
  <pricepoint>
    <esid>
      ENG.GPL.DAY_AHEAD.PROMPT.PH.M
    </esid>
    <observationdate>20120123</observationdate>
    <observationtime>0000</observationtime>
    <price>22.1250</price>
    <quote>Q</quote>
  </pricepoint>
  <pricepoint>
    <esid>
      ENG.NBP.DAY_AHEAD.PROMPT.PH.M
    </esid>
    <observationdate>20120123</observationdate>
    <observationtime>0000</observationtime>
    <price>53.8500</price>
    <quote>Q</quote>
  </pricepoint>
  <pricepoint>
    <esid>
      ENG.NCG.DAY_AHEAD.PROMPT.PH.M
    </esid>
    <observationdate>20120123</observationdate>
    <observationtime>0000</observationtime>
    <price>22.0750</price>
    <quote>Q</quote>
  </pricepoint>
  <pricepoint>
    <esid>
      ENG.TTF.DAY_AHEAD.PROMPT.PH.M
    </esid>
    <observationdate>20120123</observationdate>
    <observationtime>0000</observationtime>
    <price>21.9500</price>
    <quote>Q</quote>
  </pricepoint>
  <pricepoint>
    <esid>
      ENG.ZEEBRUGGE.DAY_AHEAD.PROMPT.PH.M
    </esid>
    <observationdate>20120123</observationdate>
    <observationtime>0000</observationtime>
    <price>53.6500</price>
    <quote>Q</quote>
  </pricepoint>
</ns0:prices>

我想将其映射到以下对象:

[Serializable]
public class Prices 
{

    public List<Pricepoint> prices { get; set; }
}

[Serializable]
public class Pricepoint
{

    public string Esid { get; set; }

    public DateTime Observationdate { get; set; }

    public int Observationtime { get; set; }

    public double Price { get; set; }

    public string Quote { get; set; }

}

使用以下方法:

    public static object Deserialize(Type typeToDeserialize,byte[] bytes)
    {
        var mem = new MemoryStream(bytes);
        var ser = new XmlSerializer(typeToDeserialize);
        return ser.Deserialize(mem);
    }

由 Deserialize(typeof(Prices), byteArrayofXMLfile); 调用

但是我确实收到了关于 xml 的命名空间行的错误:

There is an error in XML document (3, 2)

我不知道我做错了什么？

编辑:刚刚重新阅读，发现您在询问命名空间。使用 XmlRootAttribute 的 Namespace 属性，如下所示。

您需要通过属性告诉 XmlSerializer 哪些标签映射到哪些属性:

[Serializable]
[XmlRoot(Namespace = "http://www.ZomboCorp.com/", ElementName="prices")]
public class Prices 
{
    [XmlElement("pricepoint")]
    public List<Pricepoint> prices { get; set; }
}

[Serializable]
public class Pricepoint
{

    [XmlElement("esid")]
    public string Esid { get; set; }

    [XmlElement("observationdate")]
    public DateTime Observationdate { get; set; }

    [XmlElement("observationtime")]
    public int Observationtime { get; set; }

    [XmlElement("price")]
    public double Price { get; set; }

    [XmlElement("quote")]
    public string Quote { get; set; }

}
