When overridden in a derived class, creates a new part in the package.
Assembly: WindowsBase (in WindowsBase.dll)
protected abstract PackagePart CreatePartCore( Uri partUri, string contentType, CompressionOption compressionOption )
- Type: System.Uri
The uniform resource identifier (URI) for the part being created.
- Type: System.String
The content type of the data stream.
- Type: System.IO.Packaging.CompressionOption
The compression option for the data stream.
Return ValueType: System.IO.Packaging.PackagePart
The created part.
The derived 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 of the ZipPackage class to create a new part in a ZIP file.
For the default ZipPackage derived class, the 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 implementation should make no assumptions about the order or operations performed by the CreatePart method that calls it.
