XmlRootAttribute.ElementName プロパティ

XmlSerializer クラスの Serialize メソッドおよび Deserialize メソッドによって生成および認識される XML 要素名を取得または設定します。

名前空間: System.Xml.Serialization
アセンブリ: System.Xml (system.xml.dll 内)
構文

Visual Basic (宣言)

Public Property ElementName As
 String

Visual Basic (使用法)

Dim instance As XmlRootAttribute
Dim value As String

value = instance.ElementName

instance.ElementName = value

public string ElementName { get;
 set; }

C++

public:
property String^ ElementName {
    String^ get ();
    void set (String^ value);
}

/** @property */
public String get_ElementName ()

/** @property */
public void set_ElementName (String value)

JScript

public function get ElementName
 () : String

public function set ElementName
 (value : String)

プロパティ値
XML ドキュメントインスタンスで生成および認識された XML ルート要素名。既定値は、シリアル化されたクラスの名前です。

解説

生成された XML 要素の名前をクラス名とは異なる名前にする場合は、ElementName を指定します。

使用例

XmlRootAttribute クラスのインスタンスを作成し、ElementName プロパティに新しい値を設定する例を次に示します。次に、このオブジェクトを使用して、オブジェクトのシリアル化をオーバーライドするために使用される XmlAttributeOverrides オブジェクトを作成します。

Visual Basic

Public Sub SerializeOrder(filename As
 String)
   ' Create an XmlSerializer instance using the method below.
   Dim myXmlSerializer As XmlSerializer = CreateOverrider()

   ' Create the object, and set its Name property.
   Dim myStudent As New
 Student()
   myStudent.Name = "Student class1"

   ' Serialize the class, and close the TextWriter.
   Dim writer = New StreamWriter(filename)
   myXmlSerializer.Serialize(writer, myStudent)
   writer.Close()
End Sub

' Return an XmlSerializer to override the root serialization.
Public Function CreateOverrider() As
 XmlSerializer
   ' Create an XmlAttributes to override the default root element.
   Dim myXmlAttributes As New
 XmlAttributes()

   ' Create an XmlRootAttribute and set its element name and namespace.
   Dim myXmlRootAttribute As New
 XmlRootAttribute()
   myXmlRootAttribute.ElementName = "OverriddenRootElementName"
   myXmlRootAttribute.Namespace = "http://www.microsoft.com"

   ' Set the XmlRoot property to the XmlRoot object.
   myXmlAttributes.XmlRoot = myXmlRootAttribute
   Dim myXmlAttributeOverrides As New
 XmlAttributeOverrides()

   ' Add the XmlAttributes object to the XmlAttributeOverrides object.
   myXmlAttributeOverrides.Add(GetType(Student), myXmlAttributes)

   ' Create the Serializer, and return it.
   Dim myXmlSerializer As New
 XmlSerializer(GetType(Student), myXmlAttributeOverrides)
   Return myXmlSerializer
End Function

public void SerializeOrder(string
 filename)
{
   // Create an XmlSerializer instance using the method below.
   XmlSerializer myXmlSerializer = CreateOverrider();

   // Create the object, and set its Name property.
   Student myStudent = new Student();
   myStudent.Name = "Student class1";

   // Serialize the class, and close the TextWriter.
   TextWriter writer = new StreamWriter(filename);
   myXmlSerializer.Serialize(writer, myStudent);
   writer.Close();
}

// Return an XmlSerializer to override the root serialization.
public XmlSerializer CreateOverrider()
{
   // Create an XmlAttributes to override the default root element.
   XmlAttributes myXmlAttributes = new XmlAttributes();

   // Create an XmlRootAttribute and set its element name and namespace.
   XmlRootAttribute myXmlRootAttribute = new XmlRootAttribute();
   myXmlRootAttribute.ElementName = "OverriddenRootElementName";
   myXmlRootAttribute.Namespace = "http://www.microsoft.com";

   // Set the XmlRoot property to the XmlRoot object.
   myXmlAttributes.XmlRoot = myXmlRootAttribute;
   XmlAttributeOverrides myXmlAttributeOverrides = 
                                 new XmlAttributeOverrides();
   
   /* Add the XmlAttributes object to the 
   XmlAttributeOverrides object. */
   myXmlAttributeOverrides.Add(typeof(Student), myXmlAttributes);

   // Create the Serializer, and return it.
   XmlSerializer myXmlSerializer = new XmlSerializer
      (typeof(Student), myXmlAttributeOverrides);
   return myXmlSerializer;
}

C++

public:
   void SerializeOrder( String^ filename )
   {
      // Create an XmlSerializer instance using the method below.
      XmlSerializer^ myXmlSerializer = CreateOverrider();

      Student^ myStudent = gcnew Student;
      myStudent->Name = "Student class1";
      
      // Serialize the class, and close the TextWriter.
      TextWriter^ writer = gcnew StreamWriter( filename );
      myXmlSerializer->Serialize( writer, myStudent );
      writer->Close();
   }

   // Return an XmlSerializer to  the root serialization.
   XmlSerializer^ CreateOverrider()
   {
      // Create an XmlAttributes to  the default root element.
      XmlAttributes^ myXmlAttributes = gcnew XmlAttributes;

      // Add the XmlAttributes object to the XmlAttributeOverrides object.
      myXmlAttributeOverrides->Add( Student::typeid, myXmlAttributes );
      
      // Create the Serializer, and return it.
      XmlSerializer^ myXmlSerializer = gcnew XmlSerializer(
         Student::typeid, myXmlAttributeOverrides );
      return myXmlSerializer;
   }

public void SerializeOrder(String fileName)
{

    XmlSerializer myXmlSerializer = CreateOverrider();
    // Create the object, and set its name property.
    Student myStudent = new Student();

    // Serialize the class, and close the TextWriter.
    TextWriter writer = new StreamWriter(fileName);
    myXmlSerializer.Serialize(writer, myStudent);
    writer.Close();
} //SerializeOrder

// Return an XmlSerializer to override the root serialization.
public XmlSerializer CreateOverrider()
{
    // Create an XmlAttributes to override the default root element.
    XmlAttributes myXmlAttributes = new XmlAttributes();
    // Create an XmlRootAttribute and set its element name and namespace.
    XmlRootAttribute myXmlRootAttribute = new XmlRootAttribute();
    myXmlRootAttribute.set_ElementName("OverriddenRootElementName");
    myXmlRootAttribute.set_Namespace("http://www.microsoft.com");
    // Set the XmlRoot property to the XmlRoot object.
    myXmlAttributes.set_XmlRoot(myXmlRootAttribute);
    XmlAttributeOverrides myXmlAttributeOverrides =
        new XmlAttributeOverrides();

    /* Add the XmlAttributes object to the 
       XmlAttributeOverrides object. 
     */
    myXmlAttributeOverrides.Add(Student.class.ToType(), myXmlAttributes);
