The SignedInfo type exposes the following members.

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

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

  Name Description
Public Extension Method AsParallel Enables parallelization of a query. (Defined by ParallelEnumerable.)
Public Extension Method AsQueryable Converts an IEnumerable to an IQueryable. (Defined by Queryable.)
Public Extension Method Cast<TResult> Converts the elements of an IEnumerable to the specified type. (Defined by Enumerable.)
Public Extension Method 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/.

Note Note

The HostProtectionAttribute attribute applied to this type or member has the following Resources property value: MayLeakOnAbort. The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser). For more information, see the HostProtectionAttribute class or SQL Server Programming and Host Protection Attributes.
