Package.DeletePartCore Method

When overridden in a derived class, deletes a part with a given URI.

Namespace:  System.IO.Packaging
Assembly:  WindowsBase (in WindowsBase.dll)

protected abstract void DeletePartCore(
	Uri partUri


Type: System.Uri
The Uri of the PackagePart to delete.

By default, a ZipPackage derived class implementation of the abstract Package class is provided and used. In the default operation, DeletePart internally calls DeletePartCore of the ZipPackage class to perform the actual delete operation based on the physical format implemented in the derived class.

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 Inheritors

The derived class DeletePartCore implementation is called by the DeletePart method to the specified part based on the physical format implemented in the derived class.

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