wpf - WPF 中数据绑定(bind) ObservableCollection 的序列化(PropertyChangedEventManager)

Question

我试图通过数据绑定(bind)向 Listbox 显示一个列表。这是我的代码。

[Serializable]
public class RecordItem : INotifyPropertyChanged
{
    //implements of INotifyPropertyChanged
    public event PropertyChangedEventHandler PropertyChanged;
    protected void Notify(string propName) { if (this.PropertyChanged != null) { PropertyChanged(this, new PropertyChangedEventArgs(propName)); } }
}


[Serializable]
public class Records : ObservableCollection<RecordItem>
{
    public UOCRecords() { }

    public void Serialize(string path)
    {
        BinaryFormatter binForm = new BinaryFormatter();
        using (FileStream sw = File.Create(path))
        {
            binForm.Serialize(sw, this);
            sw.Close();
        }
    }

    public static UOCRecords Deserialize(string path)
    {
        //...
    }
}

它基本上工作得很好，但是当我使用数据绑定(bind)时

this.lbData.ItemsSource = myRecents;

并尝试执行序列化

this.myRecents.Serialize(recentsPath);

它失败并出现此错误:

Type 'System.ComponentModel.PropertyChangedEventManager' in Assembly 'WpfApplication1, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' is not marked as serializable.

我该如何处理？

附言。我不想序列化 PropertyChangedEvent 处理程序。我想为此标记 [NonSerializable] 属性，但我不知道该怎么做。

Answer 1

I want to marking [NonSerializable] attribute to that, but I don't know how to that.

在这种情况下，您只需使用 [field:NonSerialized] 标记事件即可。属性:

[field:NonSerialized]
public event PropertyChangedEventHandler PropertyChanged;
