XMLserializer不存储WP8中对象的所有属性

Question

基本上有DrinkCategories持有DrinkCategory的observableCollection。这个嵌套的ObservableCollection用于为WP8中的LongListSelector提供数据。

this.DrinkCategories = new ObservableCollection<DrinkCategory>();

DrinkCategory本身实现ObservableCollection并添加“Name”属性。

public class DrinkCategory : System.Collections.ObjectModel.ObservableCollection<DrinkViewModel>
{
    public string Name { get;  set; }

    public void AddDrink(DrinkViewModel drinkItem)
    {
        this.Items.Add(drinkItem);
    }
}

我的XMLserializer将“Items”存储在DrinkCategory中，但不存储“Name”。

using (IsolatedStorageFileStream stream = myIsolatedStorage.OpenFile("AvailableDrinks.xml", FileMode.Create))
{
    XmlSerializer serializer = new XmlSerializer(typeof(ObservableCollection<DrinkCategory>));
    using (XmlWriter xmlWriter = XmlWriter.Create(stream, xmlWriterSettings))
    {
        serializer.Serialize(xmlWriter, DrinkCategories);
    }
}

这是输出：

 <?xml version="1.0" encoding="utf-8"?>
  <ArrayOfArrayOfDrinkViewModel xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
   <ArrayOfDrinkViewModel>
    <DrinkViewModel>
      Properties of DVM
    </DrinkViewModel>
    <DrinkViewModel>
      Properties of DVM
    </DrinkViewModel>
    <DrinkViewModel>
      Properties of DVM
    </DrinkViewModel>
   </ArrayOfDrinkViewModel>
   <ArrayOfDrinkViewModel>
    <DrinkViewModel>
      Properties of DVM
    </DrinkViewModel>
    <DrinkViewModel>
      Properties of DVM
    </DrinkViewModel>
    <DrinkViewModel>
      Properties of DVM
    </DrinkViewModel>
   </ArrayOfDrinkViewModel>
</ArrayOfArrayOfDrinkViewModel>

我的错误在哪里？

编辑：问题似乎从“DrinkCategory”类的实现中提出，因为“DrinkCategory”的单个序列化对象持有其饮料，但不是它的名称。 XmlSerializer serializer = new XmlSerializer(typeof(DrinkCategory));
