将xml反序列化为c#对象

标签: c# xml serialization

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>

以及我希望将以下对象映射到:

[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);
    }

Deserialize(typeof(Prices), byteArrayofXMLfile);

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)

我无法弄清楚我在这里做错了什么?

修改: 只是重新阅读,看到你问的是命名空间。使用Namespace的{​​{1}}属性,如下所示。


您需要告诉XmlSerializer哪些标签通过属性映射到哪些属性:

XmlRootAttribute

这样的东西?

XmlRootAttribute r = new XmlRootAttribute("prices");
r.Namespace = "http://schemas.some.com/sadas/Output";

var ser = new XmlSerializer(typeof(Prices),r);
return ser.Deserialize(mem);

PS:您还应该考虑标记名称的大小写

通过让visual studio为我生成类来解决问题:
