我有一个使用 WPF 开发的任务栏应用程序，我只是不知道如何使用 Objectbinding 将我的对象集合绑定到 TrayPopUp。
这是我的收藏课。它是在启动时创建的，并通过反序列化 xml 文件（使用 fillCollectionFromXml 方法）填充对象：
public class OrdreCollection
{
// Fields
private ObservableCollection<Ordre> _ordreList = new ObservableCollection<Ordre>();
// Properties
public ObservableCollection<Ordre> OrdreList
{
get
{
if (_ordreList == null)
{
return new ObservableCollection<Ordre>();
}
return _ordreList;
}
set
{
_ordreList = value;
}
}
//Methods
public void fillCollectionFromXml(String filepath)
{
XmlSerializer xs = new XmlSerializer(typeof(ObservableCollection<Ordre>));
using (StreamReader rd = new StreamReader(filepath))
{
OrdreList = xs.Deserialize(rd) as ObservableCollection<Ordre>;
}
}
public void createXmlFromCollection(OrdreCollection oCol, String filepath)
{
XmlSerializer xs = new XmlSerializer(typeof(ObservableCollection<Ordre>));
using (StreamWriter wr = new StreamWriter(filepath))
{
xs.Serialize(wr, OrdreList);
}
}
//public OrdreCollection getOrdrer(String filepath)
//{
// OrdreCollection Ordrer = new OrdreCollection();
// Ordrer.fillCollectionFromXml("@../../Data/Ordrer.xml");
// return Ordrer;
//}
}
}
基类：
[Serializable]
public class Ordre : INotifyPropertyChanged
{
// INotifyPropertyChanged Member
public event PropertyChangedEventHandler PropertyChanged;
void Notify(string propName) {
if (PropertyChanged != null)
PropertyChanged(this, new PropertyChangedEventArgs(propName));
}
// Fields
private DateTime ordreDato = DateTime.Today;
private int ordreReference = 561978;
private String bestiltAf;
private List<OrdreItem> ordreItem;
//Constructors
public Ordre() { }
public Ordre(DateTime ordredato, int ordrereference, String bestiltAf, List<OrdreItem> ordreItem)
{
this.Ordredato = ordredato;
this.Ordrereference = ordrereference;
this.BestiltAf = bestiltAf;
this.OrdreItem = ordreItem;
}
//Properties
public DateTime Ordredato
{
get { return ordreDato; }
set {
ordreDato = value;
Notify("OrdreDato");
}
}
public int Ordrereference
{
get { return ordreReference; }
set {
ordreReference = value;
Notify("Ordrereference");
}
}
public String BestiltAf
{
get { return bestiltAf; }
set {
bestiltAf = value;
Notify("BestiltAf");
}
}
public List<OrdreItem> OrdreItem
{
get { return ordreItem; }
set {
ordreItem = value;
Notify("OrdreItem");
}
}
//Methods
public void addItem(OrdreItem item)
{
OrdreItem.Add(item);
}
}
[Serializable]
public class OrdreItem : INotifyPropertyChanged
{
// INotifyPropertyChanged Member
public event PropertyChangedEventHandler PropertyChanged;
void Notify(string propName)
{
if (PropertyChanged != null)
PropertyChanged(this, new PropertyChangedEventArgs(propName));
}
// Fields
private String produktKode;
private String produktNavn;
private DateTime kalibreringsDato;
private DateTime leveringsDato;
private int antal;
// Constructors
public OrdreItem() { }
public OrdreItem(String produktKode, String produktNavn, DateTime kalibreringsDato, DateTime leveringsDato, int antal)
{
this.produktKode = produktKode;
this.produktNavn = produktNavn;
this.kalibreringsDato = kalibreringsDato;
this.leveringsDato = leveringsDato;
this.antal = antal;
}
//Properties
public String ProduktKode
{
get { return produktKode; }
set {
produktKode = value;
Notify("ProduktKode");
}
}
public String ProduktNavn
{
get { return produktNavn; }
set {
produktNavn = value;
Notify("ProduktNavn");
}
}
public DateTime KalibreringsDato
{
get { return kalibreringsDato; }
set {
kalibreringsDato = value;
Notify("KalibreringsDato");
}
}
public DateTime LeveringsDato
{
get { return leveringsDato; }
set {
leveringsDato = value;
Notify("LeveringsDato");
}
}
public int Antal
{
get { return antal; }
set {
antal = value;
Notify("Antal");
}
}
}

问题在于 TrayPopup。我想在列表视图/列表框中显示我的 OrderCollecion 中所有订单的值。我希望我的问题是可以理解的，并且我的代码不会太乱。当我用 XmlDataProvider 填充列表框时，我可以让它工作，但不能用 ObjectdataProvider 或直接从集合中填充。
