The URI of the part to delete.

Exception typeCondition


partUri is a null reference (Nothing in Visual Basic).


partUri is not a valid PackagePart URI.


The package is not open (Dispose or Close has been called).


The package is read-only.

partUri must be a relative URI that consists of an absolute path which starts with a forward slash ("/") character. The absolute path is relative to the package root and is formed according to the RFC 3986Uniform Resource Identifier (URI) Generic Syntax specification. "/page1.xaml" and "/images/picture4.jpg" are examples of valid part URIs.

No exception is raised if a part with the specified partUri is not in the package. (You can use the PartExists method to determine whether a part with a specified partUri is in the package.)
