Package.CreatePartCore Method

When overridden in a derived class, creates a new part in the package.

Namespace:  System.IO.Packaging
Assembly:  WindowsBase (in WindowsBase.dll)
protected abstract PackagePart CreatePartCore(
	Uri partUri,
	string contentType,
	CompressionOption compressionOption
)

Parameters

partUri
Type: System.Uri

The uniform resource identifier (URI) for the part being created.

contentType
Type: System.String

The content type of the data stream.

compressionOption
Type: System.IO.Packaging.CompressionOption

The compression option for the data stream.

Return Value

Type: System.IO.Packaging.PackagePart
The created part.

The derived CreatePartCore method is called by the CreatePart method to create a part based on the physical format implemented in the derived class.

By default, a ZipPackage derived class implementation of the abstract Package class is provided and used. In the default operation, CreatePart internally calls CreatePartCore of the ZipPackage class to create a new part in a ZIP file.

For the default ZipPackage derived class, the CreatePartCore method only supports two compressionOption values, NotCompressed or Normal compression. Other CompressionOption values of Maximum, Fast, or SuperFast use Normal compression.

For more information about the package model and package parts, see Chapter 1 of the Open Packaging Conventions (OPC) specification available for download at http://go.microsoft.com/fwlink/?LinkID=71255.

Notes to Inheritors

The derived CreatePartCore implementation should make no assumptions about the order or operations performed by the CreatePart method that calls it.
