XmlSchemaProviderAttribute

When applied to a type, stores the name of a static method of the type that returns an XML schema and a XmlQualifiedName (or XmlSchemaType for anonymous types) that controls the serialization of the type.

XmlSchemas

Represents the collection of XML schemas.

XmlSerializationGeneratedCode

An abstract class that is the base class for XmlSerializationReader and XmlSerializationWriter and that contains methods common to both of these types.

Controls deserialization by the XmlSerializer class.

XmlSerializationReader.CollectionFixup

Holds an XmlSerializationCollectionFixupCallback delegate instance, plus the method's inputs; also supplies the method's parameters.

XmlSerializationReader.Fixup

Holds an XmlSerializationFixupCallback delegate instance, plus the method's inputs; also serves as the parameter for the method.

XmlSerializationWriter

Represents an abstract class used for controlling serialization by the XmlSerializer class.

XmlSerializer

Serializes and deserializes objects into and from XML documents. The XmlSerializer enables you to control how objects are encoded into XML.

XmlSerializerAssemblyAttribute

XmlSerializationReadCallback

Delegate used by the XmlSerializer class for deserialization of types from SOAP-encoded, non-root XML data.

XmlSerializationWriteCallback

Delegate that is used by the XmlSerializer class for serialization of types from SOAP-encoded, non-root XML data.

Remarks

The central class in the namespace is the XmlSerializer class. To use this class, use the XmlSerializer constructor to create an instance of the class using the type of the object to serialize. Once an XmlSerializer is created, create an instance of the object to serialize. You must also create an object to write the file to a document or stream, such as a Stream, TextWriter, or XmlWriter. You can then call the Serialize method to convert the object into an XML document.

To deserialize an object from an XML document, create a suitable object to read the document or stream (again, a Stream, TextWriter, or XmlWriter). Invoke the Deserialize method while casting the resulting object to the type of the original object (that was serialized).

To further control the serialization, the System.Xml.Serialization namespace contains several Attribute classes that can be applied to members of a class. For example, if a class contains a member that will be serialized as an XML element, you can apply the XmlElementAttribute attribute to the member. When applying the attribute, you can specify details such as the actual XML element name using the ElementName property. For a complete list of all the attributes, see the XmlSerializer class overview.
