DataContractSerializer.WriteEndObject Method (XmlDictionaryWriter)

Writes the closing XML element using an XmlDictionaryWriter.

Namespace:  System.Runtime.Serialization
Assembly:  System.Runtime.Serialization (in System.Runtime.Serialization.dll)

public override void WriteEndObject(
	XmlDictionaryWriter writer


Type: System.Xml.XmlDictionaryWriter

The XmlDictionaryWriter used to write the stream.


The type being serialized does not conform to data contract rules. For example, the DataContractAttribute attribute has not been applied to the type.


There is a problem with the instance being written.

The following example creates an object to serialize, an instance of the DataContractSerializer, and an instance of the XmlDictionaryWriter class. The example uses the WriteStartObject, WriteObjectContent, and WriteObjectContent methods to write the object data into the XML document. Making these calls is equivalent to making a single call of the WriteObject method. For example, a user might make the calls separately to insert additional XML attributes into the XML after calling the WriteStartObject method.

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 =

    DataContractSerializer ser =
        new DataContractSerializer(typeof(Person));

    // Use the writer to start a document.

    // Use the writer to write the root element.

    // 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);

    // Use the writer to write the end element and 
    // the end of the document.

    // Close and release the writer resources.
