如何序列化具有ObservableCollection类型属性的WPF自定义控件？

[Serializable]
public class CustomControl : Control, ISerializable
{
    // 控件的属性和字段

    public ObservableCollection<string> Items { get; set; }

    // 构造函数

    public CustomControl()
    {
        Items = new ObservableCollection<string>();
    }

    // 实现ISerializable接口的方法

    public void GetObjectData(SerializationInfo info, StreamingContext context)
    {
        info.AddValue("Items", Items);
    }

    protected CustomControl(SerializationInfo info, StreamingContext context)
    {
        Items = (ObservableCollection<string>)info.GetValue("Items", typeof(ObservableCollection<string>));
    }
}
