The uniform resource identifier (URI) of the part to retrieve.

Return Value

The requested part; or a null reference (Nothing in Visual Basic), if a part with the specified partUri is not in the package.

By default, a ZipPackage subclass implementation of the abstract Package class is provided and used. In the default operation, GetPart internally calls GetPartCore of the ZipPackage class to retrieve a part from a ZIP file.

For more information about the package model and package parts see Chapter 1 of the Open Packaging Conventions (OPC) specification available for download at

Notes to Implementers: The derived class GetPartCore implementation is called by the GetPart method to access and return the specified part based on the physical format implemented in the derived class. The derived GetPartCore implementation should make no assumptions about the order or operations performed by the GetPart method that calls it.
