名稱	Description
WriteObjectContent(XmlDictionaryWriter, Object)	使用 XmlDictionaryWriter. 來撰寫 XML 內容。
WriteObjectContent(XmlWriter, Object)	使用 XmlWriter. 來撰寫 XML 內容。

備註

WriteStartObject依序使用、 WriteObjectContent和 WriteEndObject 方法，以以下模式撰寫完整的序列化：write start、write content、write end 。這三種方法也被稱為 WriteObject 該方法。

WriteObjectContent(XmlDictionaryWriter, Object)

使用 XmlDictionaryWriter. 來撰寫 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

它們 XmlDictionaryWriter 用來撰寫 XML 內容。

graph: Object

要串連的物件。此根物件的所有子物件都會自動序列化。

例外狀況

InvalidDataContractException

被序列化的類型不符合資料合約規則。例如， DataContractAttribute 屬性尚未套用到型別。

SerializationException

實例被序列化時存在問題。

QuotaExceededException

可序列化的物件數量已超過。檢查 MaxItemsInObjectGraph 屬性。

範例

以下範例建立一個要序列化的物件、一個的實例 NetDataContractSerializer，以及一個類別的 XmlDictionaryWriter 實例。範例使用 WriteStartObject、 WriteObjectContent和 WriteEndObject 方法將物件資料寫入 XML 文件中。

public sealed class ShowWriteStartObject
{

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

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

        NetDataContractSerializer ser =
            new NetDataContractSerializer();

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

        // Use the serializer to write the start of the
        // object data. Use it again to write the object
        // data.
        ser.WriteStartObject(writer, p);
        ser.WriteObjectContent(writer, p);

        // Use the serializer to write the end of the
        // object data. Then use the writer to write the end
        // of the document.
        ser.WriteEndObject(writer);
        writer.WriteEndDocument();

        Console.WriteLine("Done");

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

NotInheritable Public Class ShowWriteStartObject
     
    Public Shared Sub WriteObjectData(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 System.Runtime.Serialization.NetDataContractSerializer()        

        ' Use the writer to start a document.
        writer.WriteStartDocument(True)
        
        ' Use the serializer to write the start of the 
        ' object data. Use it again to write the object
        ' data. 
        ser.WriteStartObject(writer, p)
        writer.WriteStartAttribute("MyAttribute")
        writer.WriteString("My Text")
        writer.WriteEndAttribute()

        ser.WriteObjectContent(writer, p)
                
        ' Use the serializer to write the end of the 
        ' object data. Then use the writer to write the end
        ' of the document.
        ser.WriteEndObject(writer)
        writer.WriteEndDocument()
        
        Console.WriteLine("Done")
        
        ' Close and release the writer resources.
        writer.Flush()
        fs.Flush()
        fs.Close()
    
    End Sub
