序列化实现INotifyPropertyChanged的类的实例时出现SerializationException

我正在尝试序列化我class级的一个领域。 对它进行序列化很好，有一个获取SerializationException。

字段是： private readonly ObservableCollection Values; 例外是

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

我的目标是Framework 3.5。

我发现了一些建议，它可能是可观察集合序列化的问题，但应该由3.5 sp1修复。

不知道如何解决这个问题，任何想法？ 谢谢。

CellVM类：

 [Serializable] public class CellVM:ANotifyPropertyChanged { public Cell model; public int X { get { return model.X; } set { model.X = value; OnPropertyChanged("X"); } } public int Y { get { return model.Y; } set { model.Y = value; OnPropertyChanged("Y"); } } public string Value { get { return model.ActualValue; } set { model.ActualValue = value; OnPropertyChanged("Value"); } } [NonSerialized] private bool _isActive; public bool IsActive { get { return _isActive; } set { _isActive = value; OnPropertyChanged("IsActive"); OnPropertyChanged("BackgroundBrush"); OnPropertyChanged("HighlightBrush"); } } public bool IsReadOnly { get { if(model.InitialValue.Equals(model.RightValue)) { return true;

} } private bool _isValueMode; public bool IsValueMode { get { return _isValueMode; } set { _isValueMode = value; OnPropertyChanged("IsValueMode"); OnPropertyChanged("ValueVisibility"); OnPropertyChanged("PossibilityVisibility"); } } [NonSerialized] private FontWeight _valueFontWeight; public FontWeight ValueFontWeight { get { return _valueFontWeight; } set { _valueFontWeight = value; OnPropertyChanged("ValueFontWeight");} } [NonSerialized] private Brush _valueColor;

animation.RepeatBehavior = RepeatBehavior.Forever; animation.AccelerationRatio = 0.5; brush.BeginAnimation(SolidColorBrush.ColorProperty, animation); return brush; } return new SolidColorBrush(Colors.Transparent); } } public Brush BackgroundBrush { get { if (IsActive) { if (!IsReadOnly) { return ColorManager.CellActive; } } if (IsInvalid) { return ColorManager.CellInvalid; } if (IsHighLighted) { return ColorManager.CellHighlighted;

animation.Completed += new EventHandler(animation_Completed); SolidColorBrush brush = new SolidColorBrush(Colors.Transparent); animation.AccelerationRatio = 0.5; BackgroundAnimationBrush = brush; brush.BeginAnimation(SolidColorBrush.ColorProperty, animation); } public void AnimateHint() { ColorAnimation animation = new ColorAnimation { From = Colors.DarkGreen, To = Colors.Transparent, Duration = new Duration(TimeSpan.FromSeconds(1.5)), AutoReverse = false }; animation.Completed += new EventHandler(animation_Completed); SolidColorBrush brush = new SolidColorBrush(Colors.Transparent); animation.AccelerationRatio = 0.5; BackgroundAnimationBrush = brush; brush.BeginAnimation(SolidColorBrush.ColorProperty, animation); } private void animation_Completed(object sender, EventArgs e) { BackgroundAnimationBrush = null; } } 

CellVM SuperClass（祖先）：

 [Serializable] public abstract class ANotifyPropertyChanged : INotifyPropertyChanged { public event PropertyChangedEventHandler PropertyChanged; protected virtual void OnPropertyChanged(string propertyName) { PropertyChangedEventHandler handler = this.PropertyChanged; if (handler != null) { var e = new PropertyChangedEventArgs(propertyName); handler(this, e); } } }

尝试通过[NonSerialized]属性标记事件PropertyChanged

下面是事件的语法:(参见MSDN ）

 [field:NonSerializedAttribute()] public event ChangedEventHandler Changed;
