Properties

	Name	Description
	ElementName	Gets or sets the XML element name given to the serialized array.
	Form	Gets or sets a value that indicates whether the XML element name generated by the XmlSerializer is qualified or unqualified.
	IsNullable	Gets or sets a value that indicates whether the XmlSerializer must serialize a member as an empty XML element with the xsi:nil attribute set to true.

Methods

	Name	Description
	Equals	Infrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Returns the hash code for this instance. (Inherited from Attribute.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	Match	When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Remarks

The XmlArrayAttribute belongs to a family of attributes that controls how the XmlSerializer serializes or deserializes an object.

You can apply the XmlArrayAttribute to a public field or read/write property that returns an array of objects, a collection, or any class that implements the IEnumerable interface.

When you apply the XmlArrayAttribute to a class member, the Serialize method of the XmlSerializer class generates a nested sequence of XML elements from that member. An XML schema document (an .xsd file) indicates such an array as a complexType. For example, if the class to be serialized represents a purchase order, you can generate an array of purchased items by applying the XmlArrayAttribute to a public field that returns an array of objects that represent order items.

If no attributes are applied to a public field or property that returns an array of complex or primitive type objects, the XmlSerializer generates a nested sequence of XML elements by default. To more precisely control what XML elements are generated, apply an XmlArrayItemAttribute and an XmlArrayAttribute to the field or property. For example, by default, the name of the generated XML element is derived from the member identifier. You can change the name of the generated XML element by setting the ElementName property.

If you serialize an array that contains items of a specific type and all the classes derived from that type, you must use the XmlArrayItemAttribute to declare each of the types.

Note:
You can use XmlArray in your code instead of the longer XmlArrayAttribute.
