[HostProtectionAttribute(SecurityAction.LinkDemand, MayLeakOnAbort = true)]
public class SignedInfo : ICollection, IEnumerable

Constructors

	Name	Description
	SignedInfo()	Initializes a new instance of the SignedInfo class.

Properties

	Name	Description
	CanonicalizationMethod	Gets or sets the canonicalization algorithm that is used before signing for the current SignedInfo object.
	CanonicalizationMethodObject	Gets a Transform object used for canonicalization.
	Count	Gets the number of references in the current SignedInfo object.
	Id	Gets or sets the ID of the current SignedInfo object.
	IsReadOnly	Gets a value that indicates whether the collection is read-only.
	IsSynchronized	Gets a value that indicates whether the collection is synchronized.
	References	Gets a list of the Reference objects of the current SignedInfo object.
	SignatureLength	Gets or sets the length of the signature for the current SignedInfo object.
	SignatureMethod	Gets or sets the name of the algorithm used for signature generation and validation for the current SignedInfo object.
	SyncRoot	Gets an object to use for synchronization.

Methods

	Name	Description
	AddReference(Reference)	Adds a Reference object to the list of references to digest and sign.
	CopyTo(Array, Int32)	Copies the elements of this instance into an Array object, starting at a specified index in the array.
	Equals(Object)	Determines whether the specified object is equal to the current object.(Inherited from Object.)
	Finalize()	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)
	GetEnumerator()	Returns an enumerator that iterates through the collection of references.
	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 the SignedInfo object.
	LoadXml(XmlElement)	Loads a SignedInfo state from an XML element.
	MemberwiseClone()	Creates a shallow copy of the current Object.(Inherited from Object.)
	ToString()	Returns a string that represents the current object.(Inherited from Object.)

Extension Methods

	Name	Description
	AsParallel()	Overloaded. Enables parallelization of a query.(Defined by ParallelEnumerable.)
	AsQueryable()	Overloaded. Converts an IEnumerable to an IQueryable.(Defined by Queryable.)
	Cast<TResult>()	Casts the elements of an IEnumerable to the specified type.(Defined by Enumerable.)
	OfType<TResult>()	Filters the elements of an IEnumerable based on a specified type.(Defined by Enumerable.)

The SignedInfo class represents the <SignedInfo> element of an XML signature defined by the XML digital signature specification. The <SignedInfo> element, which is a subelement of the <Signature> element, contains the canonicalization method used for signing, the algorithm used for signing and validation, and references that describe a digital signature.

For most scenarios, you should use the SignedInfo class available from the SignedInfo property to sign and verify XML digital signatures.

For more information about the <SignedInfo> element, see the World Wide Web Consortium (W3C) specification at www.w3.org/TR/xmldsig-core/.
