When overridden in a derived class, returns the part addressed by a given URI.

protected:
 abstract System::IO::Packaging::PackagePart ^ GetPartCore(Uri ^ partUri);

protected abstract System.IO.Packaging.PackagePart GetPartCore (Uri partUri);

protected abstract System.IO.Packaging.PackagePart? GetPartCore (Uri partUri);

abstract member GetPartCore : Uri -> System.IO.Packaging.PackagePart

Protected MustOverride Function GetPartCore (partUri As Uri) As PackagePart

Parameters

partUri: Uri

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

Returns

PackagePart

The requested part; or null, if a part with the specified partUri is not in the package.

Remarks

By default, a ZipPackage derived 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 https://www.ecma-international.org/publications-and-standards/standards/ecma-376/.

Notes to Implementers

The derived class GetPartCore(Uri) implementation is called by the GetPart(Uri) method to access and return the specified part based on the physical format implemented in the derived class.

The derived GetPartCore(Uri) implementation should make no assumptions about the order or operations performed by the GetPart(Uri) method that calls it.
