Question

我尝试反序列化根据相同模式构建的不同XML文档，是的，我是这个主题的新手。我设法检索一些自动生成的代码，使用xsd文件作为“类型定义语言”（VS2013），对我来说它看起来没问题，基本上它正在工作，这意味着我可以启动程序。但是，我的程序没有输出，通过调试我可以看到最重要的字段没有填充。这是情况（原始生成的代码和XML当然要长得多，但我切入产生问题的类）：

XML：

<?xml version="1.0" encoding="UTF-8"?>
<mainDatas 
  xmlns="http://www.myNamespace.com/"
  xmlns:ons="http://www.myOtherNamespace.com/"
  xmlns:aan="http://www.andAnotherNamespace.com/">
  <contains>
    <ons:FeatureCollection aan:id="UHL">
      <aan:boundedBy>999.9</aan:boundedBy>
      <aan:featureMember>
        <myClass1 aan:id="XXX0001">
        </myClass1>
      </aan:featureMember>
        <myClass2 aan:id="XXX0002">
        </myClass2>
      </aan:featureMember>
        <myClass1 aan:id="XXX0003">
        </myClass1>
      </aan:featureMember>
    </ons:FeatureCollection>
  </contains>
</mainDatas>

很抱歉发布了那么多自动生成的代码。我试图尽可能地省略，但由于我很无能，我不确定什么是必要的，什么不是。

现在我的工作：

XmlSerializer serializer = new XmlSerializer(typeof(mainDatas));
XmlTextReader reader = new XmlTextReader(@".\myData.xml");
mainDatas dataObject = (mainDatas)serializer.Deserialize(reader);

FeaturePropertyType[] allObjects = dataObject.contain.FeatureCollection.featureMember;

foreach(FeaturePropertyType feature in allObjects)
{
   if (feature.Item != null && feature.Item.GetType() == typeof(myClass1))
   {
        this.doSomething((myClass1)feature.Item));
   }
   else
   {
        this.doSomethingElse();
   }
}

调试时，它显示allObjects包含3个FeaturePropertyType类型的项目（即xml-sheet中myClass1和myClass2的数量为可疑）但这些项目的属性Item为null。

当我在互联网上搜索时，许多人认为它可能是命名空间的问题。所以我尝试了一点点来回改变它但没有成功。无论如何，我不认为在自动生成的代码中进行更改是一个好主意。

如果有人能就这个问题给我一些建议，我会很高兴。

问候 TM

编辑：我不得不编辑我的代码，因为我忘了用myClass1和myClass2编写AbstractFeatureType的继承。
