Syntax

C++

[HostProtectionAttribute(SecurityAction::LinkDemand, MayLeakOnAbort = true)]
public ref class DataReference sealed : EncryptedReference

Constructors

	Name	Description
	DataReference()	Initializes a new instance of the DataReference class.
	DataReference(String^)	Initializes a new instance of the DataReference class using the specified Uniform Resource Identifier (URI).
	DataReference(String^, TransformChain^)	Initializes a new instance of the DataReference class using the specified Uniform Resource Identifier (URI) and a TransformChain object.

Properties

	Name	Description
	CacheValid	Gets a value that indicates whether the cache is valid.(Inherited from EncryptedReference.)
	TransformChain	Gets or sets the transform chain of an EncryptedReference object.(Inherited from EncryptedReference.)
	Uri	Gets or sets the Uniform Resource Identifier (URI) of an EncryptedReference object.(Inherited from EncryptedReference.)

Methods

	Name	Description
	AddTransform(Transform^)	Adds a Transform object to the current transform chain of an EncryptedReference object.(Inherited from EncryptedReference.)
	Equals(Object^)	Determines whether the specified object is equal to the current object.(Inherited from Object.)
	GetHashCode()	Serves as the default hash function. (Inherited from Object.)
	GetType()	Gets the Type of the current instance.(Inherited from Object.)
	GetXml()	Returns the XML representation of an EncryptedReference object.(Inherited from EncryptedReference.)
	LoadXml(XmlElement^)	Loads an XML element into an EncryptedReference object.(Inherited from EncryptedReference.)
	ToString()	Returns a string that represents the current object.(Inherited from Object.)

Remarks

The DataReference class represents the <DataReference> element that contains the location of encrypted data used with XML encryption.

<DataReference> elements are used to refer to <EncryptedData> elements that were encrypted using the key defined in the enclosing <EncryptedKey> element. Multiple <DataReference> elements can occur if multiple <EncryptedData> elements exist that are encrypted using the same key.

For more information about XML encryption standards, see http://www.w3.org/TR/xmlenc-core/.

Examples

The following code example demonstrates how to use the DataReference class to encrypt and decrypt multiple XML elements using different session keys.
