Public Shared Function GetSourcePartUriFromRelationshipPartUri (relationshipPartUri As Uri) As Uri

Parameters

relationshipPartUri

Uri

The URI of the relationship part to return the SourceUri from.

Returns

Uri

The SourceUri of the PackagePart from the relationship with the specified relationshipPartUri.

Exceptions

ArgumentNullException

relationshipPartUri is null.

ArgumentException

relationshipPartUri is an absolute URI.

-or-

relationshipPartUri syntax is not valid for a PackagePart.

-or-

relationshipPartUri does not reference a relationship part.

-or-

The SourceUri of the relationship part references another relationship part (not valid).

Remarks

The SourceUri property of a relationship part must identify either the Package ("/") or a PackagePart that is not a PackageRelationship.

For example, if the package part "/files/document.xaml" is the source owner of the relationship part "/files/_rels/document.xaml.rels", calling GetSourcePartUriFromRelationshipPartUri with the relationshipPartUri parameter of "/files/_rels/document.xaml.rels" returns the SourceUri of "/files/document.xaml".
