问题：
在C中将Xml反序列化为对象#
徐昊焜
我想序列化一些XML。我的代码运行正常，但序列化不成功，对象为空，而不是填充数据。该值只是类型值：{OrangeCdToCollectorz.OrangeCd}。我怀疑我的阶级定义。以下是我正在序列化的类：
[Serializable, XmlRoot(ElementName = "Collection")]

这是我的代码，尝试使用几种众所周知的技术对相同的XML进行反序列化，无论是作为字符串const还是来自文件：
XmlSerializer serializer = new XmlSerializer(typeof(OrangeCd));
using (TextReader reader = new StringReader(testData))
{
OrangeCd orangeCd = (OrangeCd)serializer.Deserialize(reader);
}
// Show the dialog and get result.
DialogResult result = openFileDialog1.ShowDialog();
if (result == DialogResult.OK) // Test result.
{
string file = openFileDialog1.FileName;
try
{
var ser = new XmlSerializer(typeof(OrangeCd));
using (var reader = XmlReader.Create(file))
{
var wrapper = (OrangeCd)ser.Deserialize(reader);
XmlDocument _Doc = new XmlDocument();
_Doc.Load(file);
XmlSerializer deserializer = new XmlSerializer(typeof(OrangeCd));
using (TextReader textReader = new StringReader(_Doc.OuterXml))
{
OrangeCd XmlData = (OrangeCd)deserializer.Deserialize(textReader);
}
ser = new XmlSerializer(typeof(OrangeCd));
wrapper = (OrangeCd)ser.Deserialize(new StringReader(_Doc.OuterXml));
_Doc = new XmlDocument();
_Doc.Load(file);
ser = new XmlSerializer(typeof(OrangeCd));
wrapper = (OrangeCd)ser.Deserialize(new XmlNodeReader(_Doc.DocumentElement));
}
}
catch (IOException ioException)
{
Console.WriteLine(ioException.Message); // <-- For debugging use.
}
}

我需要反序列化成OrangeCd。收藏。不是OrangeCd，正如@Hadriel指出的那样。
陈铭晨
您的OrangeCd类没有任何属性，因此它实际上是一个空类，尽管您在其中声明了内部类。
鲁鸿
可能您想要做的是反序列化为OrangeCd。集合，没有进入橙色ECD
