WriteObjectContent(XmlDictionaryWriter, Object)

來源:

DataContractSerializer.cs

使用 XmlDictionaryWriter 寫入 XML 內容。

public:
 override void WriteObjectContent(System::Xml::XmlDictionaryWriter ^ writer, System::Object ^ graph);

public override void WriteObjectContent (System.Xml.XmlDictionaryWriter writer, object? graph);

override this.WriteObjectContent : System.Xml.XmlDictionaryWriter * obj -> unit

Public Overrides Sub WriteObjectContent (writer As XmlDictionaryWriter, graph As Object)

參數

writer

XmlDictionaryWriter

用於寫入資料流的 XmlDictionaryWriter。

graph

Object

要寫入至資料流的物件。

例外狀況

InvalidDataContractException

正在序列化的型別不符合資料合約規則。 例如，DataContractAttribute 屬性尚未套用至此型別。

SerializationException

正在寫入的執行個體發生問題。

範例

下列範例會建立要序列化的物件、DataContractSerializer 的執行個體和 XmlDictionaryWriter 類別的執行個體。 這個範例使用 WriteStartObject、WriteObjectContent 和 WriteObjectContent 方法，將物件資料寫入 XML 文件。

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

WriteObjectContent(XmlWriter, Object)

來源:

DataContractSerializer.cs

使用 XmlWriter 寫入 XML 內容。

public:
 override void WriteObjectContent(System::Xml::XmlWriter ^ writer, System::Object ^ graph);

public override void WriteObjectContent (System.Xml.XmlWriter writer, object? graph);

override this.WriteObjectContent : System.Xml.XmlWriter * obj -> unit

Public Overrides Sub WriteObjectContent (writer As XmlWriter, graph As Object)

參數

writer

XmlWriter

用於寫入資料流的 XmlWriter。

graph

Object

要寫入至資料流的物件。

例外狀況

InvalidDataContractException

正在序列化的型別不符合資料合約規則。 例如，DataContractAttribute 屬性尚未套用至此型別。

SerializationException

正在寫入的執行個體發生問題。
