Properties

Name Description
Count { get; } Gets the number of metadata properties.
DigestAlgorithm { get; } Gets the message digest algorithm, and any associated parameters, used by the signer.
Item { get; } Gets the MetadataProperty with the specified name.
Keys { get; } Gets a collection of the metadata property names.
MetadataType { get; } Gets the metadata type.
PropertyDescriptors { get; } Gets a collection of descriptors that contain information about properties accessible through the GroupDocs.Metadata search engine.
SignatureAlgorithm { get; } Gets the signature algorithm, and any associated parameters, used by the signer to generate the digital signature.
SignatureValue { get; } Gets the result of digital signature generation, using the message digest and the signer’s private key.
SignedAttributes { get; } Gets the collection of attributes that are signed.
SignerIdentifier { get; } Gets the signer’s certificate (and thereby the signer’s public key) raw data.
SigningTime { get; } Gets the time at which the signer (purportedly) performed the signing process.
UnsignedAttributes { get; } Gets the collection of attributes that are not signed.

Methods

Name Description
AddProperties(Func<MetadataProperty, bool>, PropertyValue) Adds known metadata properties satisfying the specified predicate. The operation is recursive so it affects all nested packages as well.
Contains(string) Determines whether the package contains a metadata property with the specified name.
virtual FindProperties(Func<MetadataProperty, bool>) Finds the metadata properties satisfying the specified predicate. The search is recursive so it affects all nested packages as well.
GetEnumerator() Returns an enumerator that iterates through the collection.
virtual RemoveProperties(Func<MetadataProperty, bool>) Removes metadata properties satisfying the specified predicate.
virtual Sanitize() Removes writable metadata properties from the package. The operation is recursive so it affects all nested packages as well.
SetProperties(Func<MetadataProperty, bool>, PropertyValue) Sets known metadata properties satisfying the specified predicate. The operation is recursive so it affects all nested packages as well. This method is a combination of AddProperties and UpdateProperties. If an existing property satisfies the predicate its value is updated. If there is a known property missing in the package that satisfies the predicate it is added to the package.
UpdateProperties(Func<MetadataProperty, bool>, PropertyValue) Updates known metadata properties satisfying the specified predicate. The operation is recursive so it affects all nested packages as well.
