次のXML構造の例を反映するac＃クラスを作成する方法を誰かが提案できますか？基本的に、要素Value内のサブ要素には、整数要素または文字列要素のいずれかを含めることができます。

<Preferences>
   <Preference>
      <Tag>CY3A</Tag>
      <Precedence>XML</Precedence>
      <Value>
         <Length>4</Length>
         <Integer>0</Integer>
      </Value>
   </Preference>    
   <Preference>
      <Tag>CYRV</Tag>
      <Precedence>XML</Precedence>
      <Value>
         <Length>16</Length>
         <String>0000 00 @00000</String>
      </Value>
   </Preference>
</Preferences>

次のようにクラスを定義しようとしましたが、探しているものになりませんでした。不要なd要素を生成します。

public class ProgrammingConfiguration
{
   public int Version { get; set; }
   public preferences Preferences { get; set; }
}

public class preferences
{
   public preference Preference { get; set; }
}

public class preference
{
   public string Tag { get; set; }
   public string Precedence { get; set; }                                     
   public value Value { get; set; }
}

public class value
{
   [XmlElement]
   public int Length;

   [XmlElement(Type = typeof(Integer)),
    XmlElement(Type = typeof(HexBinary))]
   public object datafield;
}

public class Integer
{          
   public string d;            
}  

public class String
{            
   public string d;
}

私は通常、xsdを作成してから、xsd.exeツールを使用してxsdから.csクラスファイルを作成します。

xsd.exeは、VisualStudioに付属しているユーティリティです。

http://quickstart.developerfusion.co.uk/quickstart/howto/doc/xmlserialization/XSDFromCls.aspxをご覧ください

しかし、XMLからもそれを行うことができます

文字列と整数の問題を解決するには、xsdにxs：choiceフィールドを追加します。これにより、「アイテム」が生成され、必要に応じてIntまたはStringとしてキャストできます。http://msdn.microsoft.com/en-us/library/exchange/bb426064(v=exchg.140).aspxをご覧ください

<xs:complexType name="FindItemParentType">
  <xs:choice>
    <xs:element name="Items" type="t:ArrayOfRealItemsType"/>
    <xs:element name="Groups" type="t:ArrayOfGroupedIetmsType"/>
  </xs:choice>
  <xs:attributeGroup ref="t:FindResponsePagingAttributes"/>
</xs:complexType>

FindItemParentType fipt = new FindItemParentType();
object obj = fipt.Item;
if (obj is ArrayOfGroupedItemsType)
{
    ArrayOfGroupedItemsType groupedItems = (obj as ArrayOfGroupedItemsType);
    //TODO: Write code to handle grouped items.
}
else if (obj is ArrayOfRealItemsType)
{
    ArrayOfRealItemsType items = (obj as ArrayOfRealItemsType);
    //TODO: Write code to handle items.
}
