我将显示在主页上的项目存储为XML字符串(在设置中)。
<?xml version=""1.0""?>
<HomePageItemList>
<PlantHomePageItem>
<Name>Plant1</Name>
</PlantHomePageItem>
<PlantHomePageItem>
<Name>Plant2</Name>
</PlantHomePageItem>
<AdminHomePageItem>
<Name>Admin1</Name>
</AdminHomePageItem>
</HomePageItemList>
有些项目代表工厂PlantHomePageItem
,其他项目代表管理工具AdminHomePageItem
。两者都继承了相同的基类HomePageItem
[XmlRoot("HomePageItemList")]
public class TestSerialization
{
[XmlArray("HomePageItemList")]
[XmlArrayItem("PlantHomePageItem", Type = typeof(PlantHomePageItem))]
[XmlArrayItem("AdminHomePageItem", Type = typeof(AdminHomePageItem))]
public List<HomePageItem> HomePageItemList { get; set; }
}
[XmlInclude(typeof(PlantHomePageItem))]
[XmlInclude(typeof(AdminHomePageItem))]
public class HomePageItem
{
[XmlElement("Name")]
public string Name { get; set; }
}
public class PlantHomePageItem : HomePageItem { }
public class AdminHomePageItem : HomePageItem { }
当我尝试反序列化它时,我没有运行时错误,只是一个空对象......
MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(XML));
XmlSerializer xs = new XmlSerializer(typeof(TestSerialization));
TestSerialization obj = (TestSerialization)xs.Deserialize(ms);
Console.WriteLine(obj.HomePageItemList.Count);
foreach (var item in obj.HomePageItemList)
{
Console.WriteLine("{0}: {1}", item.GetType().Name, item.Name);
}

将您的TestSerialization
课程更改为此...
[XmlRoot("HomePageItemList")]
public class TestSerialization
{
[XmlElement("PlantHomePageItem", Type = typeof(PlantHomePageItem))]
[XmlElement("AdminHomePageItem", Type = typeof(AdminHomePageItem))]
public List<HomePageItem> HomePageItemList { get; set; }
}
