Remarks

The TransformChain class contains a list of Transform objects that determine how to order XML data before creating a digest.

Use the TransformChain class whenever you need to add one or more transform objects to an encrypted XML document or to a signed XML document.

Both the Reference class and the EncryptedReference class contain a TransformChain object. You can add a Transform object to the Reference class by calling the AddTransform method. You can add a Transform object to the EncryptedReference class by calling the AddTransform method. You can also create a TransformChain object manually and pass it to either the TransformChain property or the TransformChain property.

If you want to sign only a portion of an XML document, you can use a transform to identify the XML elements you intend to sign. Note that the Uri property and the Uri property automatically create internal transforms that allow you to sign a portion of a document.

For more information about transforms, see the XMLDSIG specification or the XML encryption specification, which are available from the W3C website.

Constructors

TransformChain()

Initializes a new instance of the TransformChain class.

Properties

Count	Gets the number of transforms in the TransformChain object.
Item[Int32]	Gets the transform at the specified index in the TransformChain object.
