奇怪的反序列化问题

Question

我已经使用xsd.exe从XSD Schema创建了类（也尝试使用xsd2code，它们以一种立即工作的方式获得更好的结果，并且使用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找到，样本文件可以在http://landxml.org/schema/LandXML-1.1/samples/AASHTO%20SDMS/MntnRoad.xml找到。

我的反序列化代码如下：

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，我就不能轻易做到这一点。如果我想访问myFile.xml中的某些Alignment对象属性，则代码与此类似：

 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反序列化为类时的方法。我的想法就像（对于同一个元素）：

var c = LandXML.Alignments.Alignment.CoordGeometry.Curve.rot

我不知道我做错了什么，我尝试过更简单的模式，这段代码运行良好。请提前帮助和tnx！

这是我班上的顶级，我认为这种List类型会产生麻烦。在我生成的类中有一个更相似的代码

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("CoordinateSystem", typeof(CoordinateSystem))]
        [System.Xml.Serialization.XmlElementAttribute("FeatureDictionary", typeof(FeatureDictionary))]
        [System.Xml.Serialization.XmlElementAttribute("GradeModel", typeof(GradeModel))]
        [System.Xml.Serialization.XmlElementAttribute("Monuments", typeof(Monuments))]
        [System.Xml.Serialization.XmlElementAttribute("Parcels", typeof(Parcels))]
        [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;
            }
        }
