Public Overrides Sub WriteEndObject (writer As XmlDictionaryWriter)

Parametry

writer

XmlDictionaryWriter

Používá XmlDictionaryWriter se k zápisu datového proudu.

Atributy

RequiresDynamicCodeAttribute RequiresUnreferencedCodeAttribute

Výjimky

InvalidDataContractException

Typ serializovaný neodpovídá pravidlům kontraktu dat. Například atribut DataContractAttribute nebyl použit na typ.

SerializationException

Došlo k problému s zápisem instance.

Příklady

Následující příklad vytvoří objekt pro serializaci, instanci DataContractSerializera instanci XmlDictionaryWriter třídy. Příklad používá WriteStartObject, WriteObjectContenta WriteObjectContent metody k zápisu dat objektu do dokumentu XML. Provádění těchto volání je ekvivalentní provedení jediného WriteObject volání metody. Uživatel může například volat samostatně, aby po volání WriteStartObject metody vložil do XML další atributy XML.

public static void WriteObjectContentInDocument(string path)
{
    // Create the object to serialize.
    Person p = new Person("Lynn", "Tsoflias", 9876);

    // Create the writer object.
    FileStream fs = new FileStream(path, FileMode.Create);
    XmlDictionaryWriter writer =
        XmlDictionaryWriter.CreateTextWriter(fs);

    DataContractSerializer ser =
        new DataContractSerializer(typeof(Person));

    // Use the writer to start a document.
    writer.WriteStartDocument(true);

    // Use the writer to write the root element.
    writer.WriteStartElement("Company");

    // Use the writer to write an element.
    writer.WriteElementString("Name", "Microsoft");

    // Use the serializer to write the start,
    // content, and end data.
    ser.WriteStartObject(writer, p);
    ser.WriteObjectContent(writer, p);
    ser.WriteEndObject(writer);

    // Use the writer to write the end element and
    // the end of the document.
    writer.WriteEndElement();
    writer.WriteEndDocument();

    // Close and release the writer resources.
    writer.Flush();
    fs.Flush();
    fs.Close();
}

Public Shared Sub WriteObjectContentInDocument(ByVal path As String) 
    ' Create the object to serialize.
    Dim p As New Person("Lynn", "Tsoflias", 9876)
    
    ' Create the writer.
    Dim fs As New FileStream(path, FileMode.Create)
    Dim writer As XmlDictionaryWriter = XmlDictionaryWriter.CreateTextWriter(fs)
    
    Dim ser As New DataContractSerializer(GetType(Person))
    
    ' Use the writer to start a document.
    writer.WriteStartDocument(True)
    ' Use the writer to write the root element.
    writer.WriteStartElement("Company")
