反序列化此XML字符串的正确方法是什么？(What is the correct way to deserialize this XML string?)

我将显示在我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>

一些项目代表植物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); }

提供整个事物的.NET小提琴： https ： //dotnetfiddle.net/f51b0K

I store the items displayed on my homepage as an XML string (in the settings).

<?xml version=""1.0""?> <HomePageItemList> <PlantHomePageItem> <Name>Plant1</Name> </PlantHomePageItem> <PlantHomePageItem> <Name>Plant2</Name> </PlantHomePageItem> <AdminHomePageItem> <Name>Admin1</Name> </AdminHomePageItem> </HomePageItemList>

Some items represent a plant PlantHomePageItem, others an admin tool AdminHomePageItem. Both inherit the same base class 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 { }

When I try an deserialize it, I have no runtime error, just an empty object...

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); }

最满意答案

将TestSerialization类更改为此...

[XmlRoot("HomePageItemList")] public class TestSerialization { [XmlElement("PlantHomePageItem", Type = typeof(PlantHomePageItem))] [XmlElement("AdminHomePageItem", Type = typeof(AdminHomePageItem))] public List<HomePageItem> HomePageItemList { get; set; } }

你修改过的例子......

Change your TestSerialization class to this...

[XmlRoot("HomePageItemList")] public class TestSerialization { [XmlElement("PlantHomePageItem", Type = typeof(PlantHomePageItem))] [XmlElement("AdminHomePageItem", Type = typeof(AdminHomePageItem))] public List<HomePageItem> HomePageItemList { get; set; } }

Your modified example...
