XmlSerializer.Serialize Method (XmlWriter, Object, XmlSerializerNamespaces, String)

Note: This method is new in the .NET Framework version 2.0.

Serializes the specified object and writes the XML document to a file using the specified XmlWriter and references the specified namespaces and encoding style.

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

public void Serialize (
	XmlWriter xmlWriter,
	Object o,
	XmlSerializerNamespaces namespaces,
	string encodingStyle
public void Serialize (
	XmlWriter xmlWriter, 
	Object o, 
	XmlSerializerNamespaces namespaces, 
	String encodingStyle
public function Serialize (
	xmlWriter : XmlWriter, 
	o : Object, 
	namespaces : XmlSerializerNamespaces, 
	encodingStyle : String



The XmlWriter used to write the XML document.


The object to serialize.


The XmlSerializerNamespaces referenced by the object.


The encoding style of the serialized XML.

Exception typeCondition


An error occurred during serialization. The original exception is available using the InnerException property.

When the Serialize method is invoked, the public fields and read/write properties of an object are converted into XML. Methods, indexers, private fields, and read-only properties are not serialized. To serialize all fields and properties, both public and private, use the BinaryFormatter.

Use the xmlWriter parameter to specify an object that derives from the abstract XmlWriter class, which is designed to write XML documents. The XmlTextWriter derives from the XmlWriter.

Set the encodingStyle parameter to "" for SOAP version 1.1 encoding; otherwise, set it to "" for SOAP version 1.2 encoding.

Note   The XmlSerializer cannot serialize the following: arrays of ArrayList and arrays of List.
