Menulis elemen XML pembuka menggunakan penulis yang ditentukan.

Overload

WriteStartObject(XmlDictionaryWriter, Object)	Menulis elemen XML pembuka menggunakan XmlDictionaryWriter.
WriteStartObject(XmlWriter, Object)	Menulis elemen XML pembuka menggunakan XmlWriter.

WriteStartObject(XmlDictionaryWriter, Object)

Menulis elemen XML pembuka menggunakan XmlDictionaryWriter.

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

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

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

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

Parameter

writer

XmlDictionaryWriter

yang XmlDictionaryWriter digunakan untuk menulis elemen XML.

graph

Object

Objek yang akan diserialisasikan. Semua objek turunan dari objek akar ini secara otomatis diserialisasikan.

Pengecualian

InvalidDataContractException

jenis yang diserialisasikan tidak sesuai dengan aturan kontrak data. Misalnya, DataContractAttribute atribut belum diterapkan ke jenis .

SerializationException

ada masalah dengan instans yang sedang diserialisasikan.

QuotaExceededException

jumlah maksimum objek yang akan diserialisasikan telah terlampaui. Periksa properti MaxItemsInObjectGraph.

Contoh

Contoh berikut membuat objek untuk diserialisasikan, instans NetDataContractSerializer, dan instans XmlDictionaryWriter kelas . Contohnya menggunakan WriteStartObjectmetode , WriteObjectContent, dan WriteEndObject untuk menulis data objek ke dalam dokumen XML.

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

        ' 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
