使用指定的编写器写入 XML 内容。

重载

名称	说明
WriteObjectContent(XmlDictionaryWriter, Object)	使用 XmlDictionaryWriter.. 写入 XML 内容。
WriteObjectContent(XmlWriter, Object)	使用 XmlWriter.. 写入 XML 内容。

注解

使用WriteStartObject模式连续使用和WriteObjectContent WriteEndObject方法编写完整的序列化：写入开始、写入内容和写入结束。这三种方法也由 WriteObject 该方法调用。

WriteObjectContent(XmlDictionaryWriter, Object)

使用 XmlDictionaryWriter.. 写入 XML 内容。

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)

参数

writer: XmlDictionaryWriter

XmlDictionaryWriter用于写入 XML 内容。

graph: Object

要序列化的对象。此根对象的所有子对象都将自动序列化。

例外

InvalidDataContractException

要序列化的类型不符合数据协定规则。例如， DataContractAttribute 该属性尚未应用于该类型。

SerializationException

正在序列化的实例出现问题。

QuotaExceededException

已超出要序列化的最大对象数。请检查 MaxItemsInObjectGraph 属性。

示例

以下示例创建一个对象来序列化、类的NetDataContractSerializer XmlDictionaryWriter实例和实例。此示例使用WriteStartObject和WriteObjectContent WriteEndObject方法将对象数据写入 XML 文档。

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
