When overridden in a derived class, returns the part addressed by a given URI.
Assembly: WindowsBase (in WindowsBase.dll)
- Type: System.Uri
The uniform resource identifier (URI) of the part to retrieve.
Return ValueType: System.IO.Packaging.PackagePart

By default, a ZipPackage derived implementation of the abstract Package class is provided and used. In the default operation, GetPart internally calls 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 http://go.microsoft.com/fwlink/?LinkID=71255.Notes to Inheritors
The derived class 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 implementation should make no assumptions about the order or operations performed by the GetPart method that calls it.
