Získá nebo nastaví název elementu XML, který je generován a rozpoznán podle XmlSerializer třídy Serialize(TextWriter, Object) a Deserialize(Stream) metody, v uvedeném pořadí.

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

public string ElementName { get; set; }

member this.ElementName : string with get, set

Public Property ElementName As String

Hodnota vlastnosti

String

Název kořenového elementu XML, který je generován a rozpoznán v instanci dokumentu XML. Výchozí hodnota je název serializované třídy.

Příklady

Následující příklad vytvoří instanci XmlRootAttribute třídy a nastaví ElementName vlastnost na novou hodnotu. Objekt se pak použije k vytvoření objektu XmlAttributeOverrides , který slouží k přepsání serializace objektu.

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.

Poznámky

ElementName Zadejte, jestli se má název vygenerovaného elementu XML lišit od názvu třídy.
