只要通用字段Object的实际类型包含在XmlElement属性列表中,就可以按照预期将以下类的对象序列化为
XML:
public class SerializedObject<T> : Serializable where T : Serializable
{
[System.Xml.Serialization.XmlElement(Type = typeof(Weapon))]
[System.Xml.Serialization.XmlElement(Type = typeof(Armor))]
[System.Xml.Serialization.XmlElement(Type = typeof(QuestItem))]
public T Object;
public string ObjectId;
public int ID;
public SerializedObject() { }
public SerializedObject(T _object)
{
Object = _object;
ID = Object.Id;
ObjectId = Object.ObjectId;
}
}
问题是:
如何序列化此类的对象,包括通用字段Object,而不指定XmlElement属性中T的所有可能类型?
最佳答案 我也碰到了这个.我做的是创建一个包装类:
public static XmlDocument SerializeToXmlDocument<XmlEntity>(XmlEntity o)
{
XmlDocument xdoc;
SerializeWrapper<XmlEntity> wrapper = new SerializeWrapper<XmlEntity>();
wrapper.XmlObject = o;
XmlSerializer xs = new XmlSerializer(wrapper.GetType());
using (MemoryStream ms = new MemoryStream())
{
xs.Serialize(ms, wrapper);
xdoc = new XmlDocument();
ms.Position = 0;
xdoc.Load(ms);
}
return xdoc;
}
这是用于包装对象的类
[XmlRoot("Root")]
public class SerializeWrapper<TObject>
{
[XmlAttribute()]
public string Name { get; set; }
public TObject XmlObject { get; set; }
}
现在,您可以将其称为:
Weapon weapon = new Weapon()
var xdoc = SerializeToXmlDocument<Weapon>(weapon);
