加载带有反射值的对象

Question

下面的代码，我试图保存和加载一个播放器类和从xml文档。我有写部分工作，但我有一些麻烦与存储在playerElement中的数据重新填充播放器对象。我宁愿不使用xml序列化器类。

    public class Player
    {
       public string Name { get; set; }
       public int HitPoint { get; set; }
       public int ManaPoint { get; set; }
    }

    public Player LoadPlayer(XElement playerElement)
    {
        Player player = new Player();
        PropertyInfo[] properties = typeof(Player).GetProperties();
        foreach (XAttribute attribute in playerElement.Attributes())
        {
            PropertyInfo property = typeof(Player).GetProperty(attribute.Name.ToString());

            if (property != null)
            {

                object dataValue = Convert.ChangeType(attribute.Value, property.PropertyType);

                 property.SetValue(player, dataValue);
            }
        }
        return player;
    }

   public override void Write(Player value)
   {
        PropertyInfo[] properties = typeof(Player).GetProperties();
        XElement playerElement = new XElement(XmlChildName);
        foreach (PropertyInfo property in properties)
        {
            playerElement.Add(new XAttribute(property.Name, property.GetValue(value,   null).ToString()));
        }
        _doc.Root.Add(playerElement);
        _doc.Save(Path);
    }

我想你需要这样的东西。我将遍历反向到属性，而不是属性。如果存在带有属性名称的属性，则更改为:

PropertyInfo[] properties = typeof(Player).GetProperties();
foreach (XAttribute attribute in playerElement.Attributes())
{
    PropertyInfo pi = properties.Where(x => x.Name == attribute.Name).FirstOrDefault();
    if (pi != null)
    {
        pi.SetValue(player, attribute.Value);
    }
}
