Examples

The following example shows how to use the CreatePartUri method to define relative URIs for PackagePart elements.

// Convert system path and file names to Part URIs. In this example
// Uri partUriDocument /* /Content/Document.xml */ =
//     PackUriHelper.CreatePartUri(
//         new Uri("Content\Document.xml", UriKind.Relative));
// Uri partUriResource /* /Resources/Image1.jpg */ =
//     PackUriHelper.CreatePartUri(
//         new Uri("Resources\Image1.jpg", UriKind.Relative));
Uri partUriDocument = PackUriHelper.CreatePartUri(
                          new Uri(documentPath, UriKind.Relative));
Uri partUriResource = PackUriHelper.CreatePartUri(
                          new Uri(resourcePath, UriKind.Relative));

' Convert system path and file names to Part URIs. In this example
' Dim partUriDocument as Uri /* /Content/Document.xml */ =
'     PackUriHelper.CreatePartUri(
'         New Uri("Content\Document.xml", UriKind.Relative))
' Dim partUriResource as Uri /* /Resources/Image1.jpg */ =
'     PackUriHelper.CreatePartUri(
'         New Uri("Resources\Image1.jpg", UriKind.Relative))
Dim partUriDocument As Uri = PackUriHelper.CreatePartUri(New Uri(documentPath, UriKind.Relative))
Dim partUriResource As Uri = PackUriHelper.CreatePartUri(New Uri(resourcePath, UriKind.Relative))

Remarks

The URI of a PackagePart is always referenced from the Package root.

The returned PackagePart URI is an absolute path that always starts with "/" and conforms to the syntax defined in the Open Packaging Conventions Specification.

The following table illustrates sample cases for CreatePartUri.

partUri Returned Part URI
picture1.jpg /picture1.jpg
/picture2.jpg /picture2.jpg
a/mydoc.xaml /a/mydoc.xaml
/b/bar.xaml /b/bar.xaml
