为什么不此类属性序列？ [英] Why doesn't this class property serialize?

问题描述

[Serializable]
public class ProfilesCollection : ObservableCollection<Profile>
{  
    public ProfilesCollection()
    {            
    }
}

[Serializable]
public class Profile : ObservableCollection<SomeData>
{
    private string _name;        
    public string Name
    {
        get { return _name; }
        set
        {
            _name = value;
            OnPropertyChanged(new PropertyChangedEventArgs("Name"));
        }
    }

    public Profile()
    {
    }
}

[Serializable]
public class SomeData : INotifyPropertyChanged
{
    // some properties

    public SomeData()
    { ... }

    [field: NonSerialized]
    public event PropertyChangedEventHandler PropertyChanged;

    protected void NotifyPropertyChanged(string property)
    {
        if (PropertyChanged != null)
            PropertyChanged(this, new PropertyChangedEventArgs(property));
    }
}

我想序列化ProfilesCollection（或档案）使用的XmlSerializer对象：

I am trying to serialize ProfilesCollection (or Profile) object using XmlSerializer:

using (var writer = new StreamWriter("1.xml"))
{
    var xs = new XmlSerializer(typeof(ProfilesCollection));
    xs.Serialize(writer, _profiles);
}

不过的.xml不包含名称属性，它在配置文件类。除了一切正常。我应该怎么做才能解决这个问题？

but .xml doesn't contain Name property which is in Profile class. Everything except that is ok. What should I do to fix that?

推荐答案

在的XmlSerializer 序列化的集合，它只是着眼于集合中的项目，而不是其他属性集合类的。如果您需要序列化的名字，你需要做的是这样的：

When XmlSerializer serializes a collection, it only looks at the items in the collection, not the other properties of the collection class. If you need to serialize the name, you need to do something like this:

public class Profile
{
    private string _name;        
    public string Name
    {
        get { return _name; }
        set
        {
            _name = value;
            OnPropertyChanged(new PropertyChangedEventArgs("Name"));
        }
    }


    private readonly ObservableCollection<SomeData> _data = new ObservableCollection<SomeData>();
    public ObservableCollection<SomeData> Data
    {
        get { return _data; }
    }

    public Profile()
    {
    }
}

顺便说一句，在序列化和非序列化属性不使用的XmlSerializer ，这样你就不会需要他们（和事件没有被的XmlSerializer 反正）

BTW, the Serializable and NonSerialized attributes are not used by XmlSerializer, so you don't need them (and events are not serialized by XmlSerializer anyway)
