var serializer = new XmlSerializer(typeof(rootDB));
var reader = new XmlTextReader(Server.MapPath(Url.Content("~/Content/xml/rFactorHotlapsData.xml")));

java名前空間プレフィックスは定義されていませんが、.xmlドキュメントのxsi：type属性で使用されます。それを定義する属性をドキュメントのルートに追加すると、エラーはなくなります。

<rootDB xmlns:java="http://tempuri3.org">

後でわかったように、これに加えて、xsi：typeはクラスの生成を台無しにしています。ひどく。

XmlSerializerの使用

<listOfTrack xsi:type="java:com.prorfactor.top100.database.Track">

要素の名前はlistOfTrack、デフォルトの名前空間ではです。ただし、そのタイプはcom.prorfactor.top100.database.Track、Javaプレフィックスが参照している名前空間にあります。これは、xsi:type属性によって変更されるために発生します。xsd.exeはこれに対処できますが、少し助けが必要です。

私がそれを機能させる方法は、2つ.xsdのを作成することです。1つはJava名前空間用で、もう1つはドキュメントの名前空間用です。彼らはお互いをインポートします。例として、名前とタイプが頻繁に飛び交うドキュメントの開始を説明するビットを示します。

<rootDB xmlns="http://tempuri2.org"
        xmlns:java="http://tempuri3.org">
  <listOfCategory xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:type="java:com.prorfactor.top100.database.Category">
    <listOfTrack xsi:type="java:com.prorfactor.top100.database.Track">

私が呼び出したデフォルトの名前空間の場合http://tempuri2.org、要素はデフォルトの名前空間にあるため、スキーマは要素の名前をリストする必要があります。

  <xs:element name="rootDB" >
    <xs:complexType>
      <xs:choice minOccurs="0" maxOccurs="unbounded">
        <xs:element ref="listOfCategory" />
      </xs:choice>
    </xs:complexType>
  </xs:element>

  <xs:element name="listOfCategory"
              type="java:com.prorfactor.top100.database.Category">
  </xs:element>

  <xs:element name="listOfTrack"
              type="java:com.prorfactor.top100.database.Track">
  </xs:element>

私が呼び出したjava名前空間のスキーマには、http://tempuri3.orgxsi：typeを使用して要素に割り当てられた複合型がリストされています。

  <xs:complexType name="com.prorfactor.top100.database.Category"
        xmlns:orig="http://tempuri2.org">
    <xs:sequence>
      <xs:element ref="orig:listOfTrack" minOccurs="0" maxOccurs="unbounded" />
      <xs:element ref="orig:categoryName"/>
    </xs:sequence>
  </xs:complexType>

  <xs:complexType name="com.prorfactor.top100.database.Track"
        xmlns:orig="http://tempuri2.org">
    <xs:sequence>
      <xs:element ref="orig:slowestLapRecord" />
      <xs:element ref="orig:listOfLapRecord" minOccurs="0" maxOccurs="unbounded"/>
      <xs:element ref="orig:trackName"/>
    </xs:sequence>
  </xs:complexType>

私がコンパイルしたこれらの2つと.xsd、生成されたクラスは、.xmlファイルを逆シリアル化することに成功しました。

java名前空間を手動で追加し、さらにデフォルトの名前空間を.xmlファイルに指定する場合

したがって、正直なところ、LINQtoXMLを使用する方が良いと思います。

LINQtoXMLの使用

XDocument xElement = XDocument.Load(Server.MapPath(Url.Content("~/Content/xml/rFactorHotlapsData.xml")));

// just some selects to show how you select them
var cats = from cat in xElement.Descendants("listOfCategory")
           select new
           {
              Name = cat.Descendants("categoryName").FirstOrDefault().Value,
              Track = from track in cat.Descendants("listOfTrack")
                      select new 
                      {
                         Name = track.Descendants("trackName").FirstOrDefault().Value,
                         LapRecord = from record in cat.Descendants("listOfLapRecord")
                                     select new
                                     {
                                        driverName = record.Descendants("driverName").FirstOrDefault().Value,
                                        sessionName = record.Descendants("sessionName").FirstOrDefault().Value,
                                        date = record.Descendants("date").FirstOrDefault().Value
                                     }
                       }
           };

// And a demo of how to iterate over the result of the select
foreach (var category in cats)
{
   Console.WriteLine(category.Name);
   foreach (var track in category.Track)
   {
      Console.WriteLine("  " + track.Name);
      foreach (var lapRecord in track.LapRecord)
      {
         Console.WriteLine("      " + lapRecord.driverName);
         Console.WriteLine("      " + lapRecord.sessionName);
         Console.WriteLine("      " + lapRecord.date);
      }
   }
}
