如何强制 ListBox 重新加载 ListBoxItems 的属性

有什么方法可以强制 ObservableCollection 触发 CollectionChanged 吗？

我有一个 ObservableCollection 对象ListBox项目源，因此每次我向集合中添加/删除项目时，ListBox 都会相应更改，但是当我更改集合中某些对象的属性时，ListBox 仍然呈现旧值。

即使我确实修改了一些属性，然后向集合添加/删除对象，也没有任何反应，我仍然看到旧值。

还有其他方法可以做到这一点吗？我找到了接口 INotifyPropertyChanged，但我不知道如何使用它。

我同意马特上面的评论。这里有一小段代码展示了如何实现 INotifyPropertyChanged。

    public partial class Window1 : Window
    {
        Nicknames names;

        public Window1()
        {
            InitializeComponent();
            this.addButton.Click += addButton_Click;
            this.names = new Nicknames();
            dockPanel.DataContext = this.names;
        }

        void addButton_Click(object sender, RoutedEventArgs e)
        {
            this.names.Add(new Nickname(myName.Text, myNick.Text));
        }
}
public class Nicknames : System.Collections.ObjectModel.ObservableCollection<Nickname> { }

public class Nickname : System.ComponentModel.INotifyPropertyChanged
{
    public event System.ComponentModel.PropertyChangedEventHandler PropertyChanged;
    void Notify(string propName)
    {
        if (PropertyChanged != null)
        {
            PropertyChanged(this, new System.ComponentModel.PropertyChangedEventArgs(propName));
        }
    }

    string name;
    public string Name
    {
        get { return name; }
        set
        {
            name = value;
            Notify("Name");
        }
    }
    string nick;
    public string Nick
    {
        get { return nick; }
        set
        {
            nick = value;
            Notify("Nick");
        }
    }
    public Nickname() : this("name", "nick") { }
    public Nickname(string name, string nick)
    {
        this.name = name;
        this.nick = nick;
    }

    public override string ToString()
    {
        return Name.ToString() + " " + Nick.ToString();
    }
  }
}
