Remarks

When performing XML signing and verification, the <Transform> element describes how the signer transformed the data object that was signed. The verifier of a document then uses the <Transform> element to transform the signed data in the same manner. If the verifier cannot transform the signed data in the same manner, the document cannot be verified.

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

For more information about the <Transform> element, see the XMLDSIG specification or the XML encryption specification, which are available on the W3C website.

Constructors

Transform()

Initializes a new instance of the Transform class.

Properties

Algorithm

Gets or sets the Uniform Resource Identifier (URI) that identifies the algorithm performed by the current transform.
Context

Gets or sets an XmlElement object that represents the document context under which the current Transform object is running.
InputTypes

When overridden in a derived class, gets an array of types that are valid inputs to the LoadInput(Object) method of the current Transform object.
OutputTypes

When overridden in a derived class, gets an array of types that are possible outputs from the GetOutput() methods of the current Transform object.
PropagatedNamespaces

Gets or sets a Hashtable object that contains the namespaces that are propagated into the signature.
Resolver

Sets the current XmlResolver object.

Methods

Equals(Object)

Determines whether the specified object is equal to the current object.

(Inherited from Object)
GetDigestedOutput(HashAlgorithm)

When overridden in a derived class, returns the digest associated with a Transform object.
GetHashCode()

Serves as the default hash function.

(Inherited from Object)
GetInnerXml()

When overridden in a derived class, returns an XML representation of the parameters of the Transform object that are suitable to be included as subelements of an XMLDSIG <Transform> element.
GetOutput()

When overridden in a derived class, returns the output of the current Transform object.
GetOutput(Type)

When overridden in a derived class, returns the output of the current Transform object of the specified type.
GetType()

Gets the Type of the current instance.

(Inherited from Object)
GetXml()

Returns the XML representation of the current Transform object.
LoadInnerXml(XmlNodeList)

When overridden in a derived class, parses the specified XmlNodeList object as transform-specific content of a <Transform> element and configures the internal state of the current Transform object to match the <Transform> element.
LoadInput(Object)

When overridden in a derived class, loads the specified input into the current Transform object.
MemberwiseClone()

Creates a shallow copy of the current Object.

(Inherited from Object)
ToString()

Returns a string that represents the current object.

(Inherited from Object)
