Public Overrides Sub WriteStartObject (writer As XmlDictionaryWriter, graph As Object)
參數
- writer
- XmlDictionaryWriter
用來 XmlDictionaryWriter 撰寫 XML 起始元素。
- graph
- Object
要寫入的物件。
- 屬性
範例
以下範例建立一個要序列化的物件、一個 的實例 DataContractSerializer,以及一個類別的 XmlDictionaryWriter 實例。 範例使用 WriteStartObject、 WriteObjectContent和 WriteObjectContent 方法將物件資料寫入 XML 文件中。
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
