奇怪的反序列化问题 [英] Strange deserialization issue
问题描述
我已经使用 xsd.exe 从 XSD Schema 创建了类(也尝试过使用 xsd2code 以立即工作的方式获得更好的结果，而使用 xsd.exe 我必须调试一些错误).我使用的 XSD 架构可以在 http://www.landxml.org/schema/LandXML-1.2/LandXML-1.2.xsd ，示例文件可以在 http://landxml.org/schema/LandXML-1.1/samples/AASHTO%20SDMS/MntnRoad.xml.
I've created classes from XSD Schema using xsd.exe (also tried with xsd2code which had better results in a way that they worked immediately, and with xsd.exe I have to debug some errors). XSD Schema I've used can be found at http://www.landxml.org/schema/LandXML-1.2/LandXML-1.2.xsd , and sample file can be found at http://landxml.org/schema/LandXML-1.1/samples/AASHTO%20SDMS/MntnRoad.xml .
我的反序列化代码如下:
My code for deserialization looks like:
var mySerializer = new XmlSerializer(typeof (LandXML), new XmlRootAttribute(""));
TextReader myFileStream = new StreamReader("myFile.xml");
var myObject = (LandXML) mySerializer.Deserialize(myFileStream);
我的问题是反序列化的结果是 XmlElement 类型的项目列表，所以如果我尝试访问它们的属性，我就不容易做到这一点.例如，如果我想访问 myFile.xml 中的某些 Alignment 对象属性，则代码类似于:
My problem is that result of deserialization is list of items of type XmlElement, so if I try to access their properties, I can't easy do that. If I want to access, for example, some Alignment object attribute in myFile.xml, the code is similar to this:
var a = myObject.Items[5];
var b = (XmlElement) a;
var c = b.ChildNodes.Item(5).ChildNodes.Item(0).ChildNodes.Item(0).Attributes[0].Value;
很明显，这不是将 XML 反序列化为类的方式.我的想法就像(对于相同的元素):
It is obvious that this is not a way which is meant to be while deserializing XML to classes. My idea was like (for same element):
var c = LandXML.Alignments.Alignment.CoordGeometry.Curve.rot
我不知道我做错了什么，我尝试过使用更简单的模式，并且这段代码运行良好.请提前帮助和tnx！
I don't know what I'm doing wrong, I've tried with simpler schemas, and this code was working well. Please help and tnx in advance!

这是我班上的佼佼者，我认为这种 List 类型会产生麻烦.并且在我生成的类中有更相似的代码
this is at top of my class and I think that this List type generating troubles. And there is a more similar code in my generated classes
public class LandXML
{
private List<object> _items;
private System.DateTime _date;
private System.DateTime _time;
private string _version;
private string _language;
private bool _readOnly;
private int _landXMLId;
private string _crc;
public LandXML()
{
this._items = new List<object>();
}
[System.Xml.Serialization.XmlAnyElementAttribute()]
[System.Xml.Serialization.XmlElementAttribute("Alignments", typeof(Alignments))]
[System.Xml.Serialization.XmlElementAttribute("Amendment", typeof(Amendment))]
[System.Xml.Serialization.XmlElementAttribute("Application", typeof(Application))]
[System.Xml.Serialization.XmlElementAttribute("CgPoints", typeof(CgPoints))]

[System.Xml.Serialization.XmlElementAttribute("PipeNetworks", typeof(PipeNetworks))]
[System.Xml.Serialization.XmlElementAttribute("PlanFeatures", typeof(PlanFeatures))]
[System.Xml.Serialization.XmlElementAttribute("Project", typeof(Project))]
[System.Xml.Serialization.XmlElementAttribute("Roadways", typeof(Roadways))]
[System.Xml.Serialization.XmlElementAttribute("Surfaces", typeof(Surfaces))]
[System.Xml.Serialization.XmlElementAttribute("Survey", typeof(Survey))]
[System.Xml.Serialization.XmlElementAttribute("Units", typeof(Units))]
public List<object> Items
{
get
{
return this._items;
}
set
{
this._items = value;
}
}
