Syntax

'Declaration

[AttributeUsageAttribute(AttributeTargets.Class|AttributeTargets.Struct|AttributeTargets.Method|AttributeTargets.Interface, AllowMultiple = true)]

	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.)

Remarks

Use the XmlIncludeAttribute when you call the Serialize or Deserialize method of the XmlSerializer class.

When applying the XmlIncludeAttribute, specify the Type of the derived class. When the XmlSerializer serializes objects that include both the base and the derived class, it can then recognize both object types.

You can use the XmlIncludeAttribute to include derived classes in service description documents that are written in the Web Services Description Language (WSDL). For example, if a method returns an Object, apply the XmlIncludeAttribute to the method and specify the actual types to return.
