XmlSerializer Constructor (Type, String)


The .NET API Reference documentation has a new home. Visit the .NET API Browser on docs.microsoft.com to see the new experience.

Initializes a new instance of the XmlSerializer class that can serialize objects of the specified type into XML documents, and deserialize XML documents into objects of the specified type. Specifies the default namespace for all the XML elements.

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

public XmlSerializer(
	Type type,
	string defaultNamespace


Type: System.Type

The type of the object that this XmlSerializer can serialize.

Type: System.String

The default namespace to use for all the XML elements.

The following example constructs an XmlSerializer that serializes an object named Widget. The example sets various properties of the object before calling the Serialize method.

private void SerializeObject(string filename) {
    XmlSerializer serializer = new XmlSerializer
        (typeof(OrderedItem), "http://www.cpandl.com");

    // Create an instance of the class to be serialized.
    OrderedItem i = new OrderedItem();

    // Insert code to set property values.

    // Writing the document requires a TextWriter.
    TextWriter writer = new StreamWriter(filename);
    // Serialize the object, and close the TextWriter
    serializer.Serialize(writer, i);

private void DeserializeObject(string filename) {
    XmlSerializer serializer = new XmlSerializer
        (typeof(OrderedItem), "http://www.cpandl.com");
    // A FileStream is needed to read the XML document.
    FileStream fs = new FileStream(filename, FileMode.Open);

    // Declare an object variable of the type to be deserialized.
    OrderedItem i;

    // Deserialize the object.
    i = (OrderedItem) serializer.Deserialize(fs);

    // Insert code to use the properties and methods of the object.
