public:
 override void WriteStartObject(System::Xml::XmlDictionaryWriter ^ writer, System::Object ^ graph);
public override void WriteStartObject (System.Xml.XmlDictionaryWriter writer, object graph);
public override void WriteStartObject (System.Xml.XmlDictionaryWriter writer, object? graph);

示例

下面的示例创建要序列化的对象、DataContractSerializer 的实例以及 XmlDictionaryWriter 类的实例。The following example creates an object to serialize, an instance of the DataContractSerializer, and an instance of the XmlDictionaryWriter class. 该示例使用 WriteStartObjectWriteObjectContentWriteObjectContent 方法将对象数据写入 XML 文档。The example uses the WriteStartObject, WriteObjectContent, and WriteObjectContent methods to write the object data into the XML document.

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")
    ' 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()

End Sub
