XmlSerializer.XmlSerializer(Type, XmlRootAttribute) Constructor

Initializes a new instance of the XmlSerializer class that can serialize objects of the specified type into XML documents, and deserialize an XML document into object of the specified type. It also specifies the class to use as the XML root element.

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

public XmlSerializer (
	Type type,
	XmlRootAttribute root
)
public XmlSerializer (
	Type type, 
	XmlRootAttribute root
)
public function XmlSerializer (
	type : Type, 
	root : XmlRootAttribute
)
Not applicable.

Parameters

type

The type of the object that this XmlSerializer can serialize.

root

An XmlRootAttribute that represents the XML root element.

The root element of an XML document encloses all the other elements. By default, the object specified by the type parameter is serialized as the root element. Properties, such as the XML element name of the root element, are taken from the type object. However, the root parameter allows you to replace the default object's information by specifying an XmlRootAttribute; the object allows you to set a different namespace, element name, and so on.

The following example constructs an XmlSerializer that uses an XmlRootAttribute that contains various properties of the XML root element, such as its namespace and element name.

private void SerializeObject(string filename) {
    // Create an XmlRootAttribute, and set its properties.
    XmlRootAttribute xRoot = new XmlRootAttribute();
    xRoot.ElementName = "CustomRoot";
    xRoot.Namespace = "http://www.cpandl.com";
    xRoot.IsNullable = true;
     
    // Construct the XmlSerializer with the XmlRootAttribute.
    XmlSerializer serializer = new XmlSerializer
        (typeof(OrderedItem),xRoot);
     
    // Create an instance of the object to serialize.
    OrderedItem i = new OrderedItem();
    // Insert code to set properties of the ordered item.
     
    // Writing the document requires a TextWriter.
    TextWriter writer = new StreamWriter(filename);
     
    serializer.Serialize(writer, i);
    writer.Close();
}

private void DeserializeObject(string filename) {
    // Create an XmlRootAttribute, and set its properties.
    XmlRootAttribute xRoot = new XmlRootAttribute();
    xRoot.ElementName = "CustomRoot";
    xRoot.Namespace = "http://www.cpandl.com";
    xRoot.IsNullable = true;
     
    XmlSerializer serializer = new XmlSerializer
        (typeof(OrderedItem),xRoot);
     
    // A FileStream is needed to read the XML document.
    FileStream fs = new FileStream(filename, FileMode.Open);
    // Deserialize the object.
    OrderedItem i = (OrderedItem) serializer.Deserialize(fs);
    // Insert code to use the object's properties and methods.
}


private void SerializeObject(String filename)
{
    // Create an XmlRootAttribute, and set its properties.
    XmlRootAttribute xRoot = new XmlRootAttribute();
    xRoot.set_ElementName("CustomRoot");
    xRoot.set_Namespace("http://www.cpandl.com");
    xRoot.set_IsNullable(true);

    // Construct the XmlSerializer with the XmlRootAttribute.
    XmlSerializer serializer =
        new XmlSerializer(OrderedItem.class.ToType(), xRoot);

    // Create an instance of the object to serialize.
    OrderedItem i = new OrderedItem();

    // Insert code to set properties of the ordered item.
    // Writing the document requires a TextWriter.
    TextWriter writer = new StreamWriter(filename);
    serializer.Serialize(writer, i);
    writer.Close();
} //SerializeObject

private void DeserializeObject(String filename)
{
    // Create an XmlRootAttribute, and set its properties.
    XmlRootAttribute xRoot = new XmlRootAttribute();
    xRoot.set_ElementName("CustomRoot");
    xRoot.set_Namespace("http://www.cpandl.com");
    xRoot.set_IsNullable(true);

    XmlSerializer serializer =
        new XmlSerializer(OrderedItem.class.ToType(), xRoot);

    // A FileStream is needed to read the XML document.
    FileStream fs = new FileStream(filename, FileMode.Open);

    // Deserialize the object.
    OrderedItem i = (OrderedItem)serializer.Deserialize(fs);
    // Insert code to use the object's properties and methods.
} //DeserializeObject
