[英]Deserialize XML with multiple namespaces to objects
我試圖將此XML反序列化為C#.NET 4.5中的對象:
<DIDL-Lite xmlns:dc="http://purl.org/dc/elements/1.1/"
xmlns:upnp="urn:schemas-upnp-org:metadata-1-0/upnp/"
xmlns="urn:schemas-upnp-org:metadata-1-0/DIDL-Lite/">
<item id="28" parentID="19" restricted="1">
<dc:creator>Alicia Keys</dc:creator>
<dc:date>2003-01-01</dc:date>
<dc:title>Gangsta Lovin' (feat. Alicia Keys)</dc:title>
</item>
</DIDL-Lite>
碼:
我沒有得到任何“項目”列表。 該對象未反序列化。
MemoryStream reader = new MemmoryStream(System.Text.Encoding.Unicode.GetBytes(Result));
var ser = new XmlSerializer(typeof(DIDLLite));
DIDLLite device = (DIDLLite)ser.Deserialize(reader);
DIDLLite
類:
[XmlRoot("DIDL-Lite", Namespace = "urn:schemas-upnp-org:metadata-1-0/DIDL-Lite/")]
public class DIDLLite {
DIDLLite() {
this.serviceItem = new List<ContainerItem>();
}
[System.Xml.Serialization.XmlArrayItem("item", typeof(ServiceListTypeService), IsNullable = false)]
List<ContainerItem> serviceItem = new List<ContainerItem>();
}
ContainerItem
類:
public class ContainerItem
{
[System.Xml.Serialization.XmlAttribute("id")]
public string id { get; set; }
[System.Xml.Serialization.XmlAttribute("parentID")]
public string parentID { get; set; }
[System.Xml.Serialization.XmlAttribute("restricted")]
public string restricted { get; set; }
[System.Xml.Serialization.XmlAttribute("searchable")]
public string searchable { get; set; }
public string title { get; set; }
}
你有幾個問題:
您定義了一個XmlArrayItem
屬性 - 但實際上,在您的XML中,您沒有任何項目列表。 如果你想使用Xml數組結構,你需要為你的XML提供類似的東西:
<DIDL-Lite .....> <Items> <item id="28" parentID="19" restricted="1"> ...... </item> <item id="29" parentID="19" restricted="1"> ...... </item> </Items> </DIDL-Lite>
所以你需要在<item>
元素周圍有一個<Items>...</Items>
包裝器。
你有這個聲明:
[XmlArrayItem("item", typeof(ServiceListTypeService), IsNullable = false)]
但是ServiceListtypeService
定義在哪里? 我沒有看到任何痕跡....
我簡化了你的代碼 - 這很好用:
[XmlRoot("DIDL-Lite", Namespace = "urn:schemas-upnp-org:metadata-1-0/DIDL-Lite/")]
public class DIDLLite
{
[XmlElement("item")]
public ContainerItem Item { get; set; }
}
public class ContainerItem
{
[XmlAttribute("id")]
public string id { get; set; }
[XmlAttribute("parentID")]
public string parentID { get; set; }
[XmlAttribute("restricted")]
public string restricted { get; set; }
[XmlAttribute("searchable")]
public string searchable { get; set; }
// you were missing these elements and their namespace
[XmlElement(Namespace = "http://purl.org/dc/elements/1.1/")]
public string creator { get; set; }
[XmlElement(Namespace = "http://purl.org/dc/elements/1.1/")]
public string date { get; set; }
[XmlElement(Namespace = "http://purl.org/dc/elements/1.1/")]
public string title { get; set; }
}
現在,當我運行你的代碼來反序列化你的XML時,我確實很好地填充了這些對象。
