static Uri ^ ResolvePartUri(Uri ^ sourcePartUri, Uri ^ targetUri);
public static Uri ResolvePartUri(Uri sourcePartUri, Uri targetUri);
static member ResolvePartUri : Uri * Uri -> Uri
Public Shared Function ResolvePartUri (sourcePartUri As Uri, targetUri As Uri) As Uri
Parameters
- targetUri
- Uri
De relatieve URI voor het doelonderdeel.
Retouren
De URI van het doelonderdeel is opgelost tussen de opgegeven sourcePartUri en de targetUri parameters.
Uitzonderingen
sourcePartUri of targetUri is null.
sourcePartUri is geen geldige deel-URI.
– of –
targetUri is geen geldige relatieve URI.
Voorbeelden
In het volgende voorbeeld ziet u hoe u de ResolvePartUri methode gebruikt.
// Open the Package.
// ('using' statement insures that 'package' is
// closed and disposed when it goes out of scope.)
using (Package package =
Package.Open(packagePath, FileMode.Open, FileAccess.Read))
{
PackagePart documentPart = null;
PackagePart resourcePart = null;
// Get the Package Relationships and look for
// the Document part based on the RelationshipType
Uri uriDocumentTarget = null;
foreach (PackageRelationship relationship in
package.GetRelationshipsByType(PackageRelationshipType))
{
// Resolve the Relationship Target Uri
// so the Document Part can be retrieved.
uriDocumentTarget = PackUriHelper.ResolvePartUri(
new Uri("/", UriKind.Relative), relationship.TargetUri);
// Open the Document Part, write the contents to a file.
documentPart = package.GetPart(uriDocumentTarget);
ExtractPart(documentPart, targetDirectory);
}
// Get the Document part's Relationships,
// and look for required resources.
Uri uriResourceTarget = null;
foreach (PackageRelationship relationship in
documentPart.GetRelationshipsByType(
ResourceRelationshipType))
{
// Resolve the Relationship Target Uri
// so the Resource Part can be retrieved.
uriResourceTarget = PackUriHelper.ResolvePartUri(
documentPart.Uri, relationship.TargetUri);
// Open the Resource Part and write the contents to a file.
resourcePart = package.GetPart(uriResourceTarget);
ExtractPart(resourcePart, targetDirectory);
}
}// end:using(Package package) - Close & dispose package.
