Add(PdfAssociatedFileRelationshipType, String, String, PdfEmbeddedFileSpecificationTree)

Adds a new PdfFileSpecification with the specified relationship and the EmbeddedFile copied from the resource specified by the filePath.

C#
VB.NET

public PdfFileSpecification Add(PdfAssociatedFileRelationshipType associatedRelationshipType, string filePath, string mediaType = null, PdfEmbeddedFileSpecificationTree embeddedFiles = null)

Public Function Add(associatedRelationshipType As PdfAssociatedFileRelationshipType, filePath As String, mediaType As String = Nothing, embeddedFiles As PdfEmbeddedFileSpecificationTree = Nothing) As PdfFileSpecification

Parameters

associatedRelationshipType: PdfAssociatedFileRelationshipType

The relationship between the component of a PDF document that refers to this PdfAssociatedFileCollection and the newly added PdfFileSpecification.

filePath: System.String

The location of the resource copied to the EmbeddedFile of a newly added PdfFileSpecification. This value is also used to resolve the Name and a key in the PdfEmbeddedFileSpecificationTree (if embeddedFiles is not null) of a newly added PdfFileSpecification.

mediaType: System.String

The media type of the embedded file.

embeddedFiles: PdfEmbeddedFileSpecificationTree

The EmbeddedFiles to which the newly created PdfFileSpecification should be added or null.

Returns

PdfFileSpecification

A newly created PdfFileSpecification with the specified relationship and the EmbeddedFile copied from the resource specified by the filePath added to the PdfAssociatedFileCollection.

Remarks

The EmbeddedFile's Size, CreationDate, ModificationDate, and MediaType properties are automatically set, if they can be resolved from the resource specified by the filePath.

Exceptions

System.ArgumentNullException

filePath is null or System.String.Empty.

AddEmpty(PdfAssociatedFileRelationshipType, String, String, PdfEmbeddedFileSpecificationTree)

Adds a new PdfFileSpecification with the specified relationship and an empty EmbeddedFile.

Use the OpenWrite(Boolean) method of the EmbeddedFile of a returned PdfFileSpecification to fill the empty EmbeddedFile.

C#
VB.NET

public PdfFileSpecification AddEmpty(PdfAssociatedFileRelationshipType associatedRelationshipType, string fileSpecificationName, string mediaType = null, PdfEmbeddedFileSpecificationTree embeddedFiles = null)

Public Function AddEmpty(associatedRelationshipType As PdfAssociatedFileRelationshipType, fileSpecificationName As String, mediaType As String = Nothing, embeddedFiles As PdfEmbeddedFileSpecificationTree = Nothing) As PdfFileSpecification

Parameters

associatedRelationshipType: PdfAssociatedFileRelationshipType

The relationship between the component of a PDF document that refers to this PdfAssociatedFileCollection and the newly added PdfFileSpecification.

fileSpecificationName: System.String

The name of a newly added PdfFileSpecification. This value is also used to resolve a key in the PdfEmbeddedFileSpecificationTree (if embeddedFiles is not null) of a newly added PdfFileSpecification.
