c# - XmlSerializer 不填充值

Question

我从 DTD(通过 XSD 和 xsd.exe)为我的 C# 项目创建了类，因此我可以轻松地将它们反序列化为代码中的模型类。

我大致是这样做的:

XmlReaderSettings readerSettings = new XmlReaderSettings();
readerSettings.DtdProcessing = DtdProcessing.Parse;

XmlReader reader = XmlReader.Create(tipsfile.FullName, readerSettings);

XmlRootAttribute xRoot = new XmlRootAttribute();
xRoot.ElementName = "Tips";
xRoot.IsNullable = true;

XmlSerializer serializer = new XmlSerializer(typeof(Tips), xRoot);
Tips tips = (Tips)serializer.Deserialize(reader);

reader.Close();

但是，在检查 tips 后，我发现它根本不包含原始 XML 文件中的任何值。另外，我尝试在 Tips 属性的 set-Body 上设置断点，但从未达到该断点，尽管我确信它在原始 XML 文件。

为什么文件没有正确反序列化到类中？我的代码中缺少什么吗？

编辑:这是 Tips.cs 文件，它是从 XSD 自动生成的

还有一个示例 XML 文件:

<!DOCTYPE Tips SYSTEM "caravan_1.dtd">

    <Chapter Country="dafghagt" Language="de">
        <Heading>fgagasgargaergarg</Heading>        
        <Section id="1">

Answer 1

        StreamReader sw = new StreamReader(fileName, false);
        XmlTextReader xmlw = new XmlTextReader(sw);
        XmlSerializer writer = new XmlSerializer(
            type,
            GetOverrides(),
            extraTypes,
            null,
            null);

        object o = writer.Deserialize(xmlw);

根据我的评论，get overrides 只是一个包含类似于您的 xml 根属性的方法，如果需要，我也可以向您展示这一点

编辑: 额外类型的示例

    public Type[] GetTypes()
    {
        return new Type[] { typeof(Class1), typeof(Class2)};
    }

EDIT2:获取覆盖返回(注意这是未经测试的)

XmlAttributes attribs = new XmlAttributes();
//attribs.XmlRoot - can edit root here (instead of xmlrootattribute)
attribs.XmlElements.Add(myAttribute);

XmlAttributeOverrides myOverride = new XmlAttributeOverrides();
myOverride.Add(typeof(Tips), "Tips", attribs);
return myOverride
