Parameter

  • linkTypes
    Typ: []

    Enthält ein Array von Link-Typen.

Rückgabewert

Typ: System.Int32

Beispiele

Im Beispiel wird den SvcObjectLinkProvider -Namespace in der Assembly für ProjectServerServices.dll Proxy verwendet. Die ConfigureClientEndPoints -Methode verwendet eine App für den WCF-Bindung, Verhalten und Endpunkt festlegen. Informationen zum Erstellen einer PSI-Proxy-Assembly und eine App finden Sie unter Prerequisites for WCF-Based Code Samples.

Hinweis

Dieses Beispiel veranschaulicht die Verwendung der CreateWebObjectLinks -Methode; Es ist keine vollständige Lösung.

Bevor Sie die Beispielanwendung ausführen, führen Sie die folgenden Schritte aus:

  1. Verwenden Sie Project Professional 2013 zum Erstellen und veröffentlichen Sie ein Projekt mit mindestens einer Aufgabe an.

  2. Verwenden Sie Project Web App , um die Projektwebsite öffnen.

  3. Erstellen Sie mindestens ein Problem oder Risiko in das Problem oder Risiko SharePoint-Liste der Projektwebsite.

  4. Ändern Sie die Konstruktor Werte entsprechend Ihrer Beispiel.

  5. Fügen Sie einen Webdienstverweis auf https://localhost/pwa/_vti_bin/Lists.asmx, und nennen Sie es WebSvcLists.

In diesem Beispiel werden die folgenden Aufgaben ausgeführt:

  • Überprüft, ob das Projekt, Vorgang und Projektwebsite vorhanden sind und ihre entsprechenden GUIDs ruft.

  • Ein Vorgang Links und einer SharePoint-Listenelement (in diesem Fall ein Problem).

  • Eine Aufgabe und ein generisches Objekt verknüpft.

  • Ruft die Liste der SharePoint-Elemente, die mit einer Aufgabe verbunden sind, und schreibt den Inhalt der ObjectLinkProvider DataSet dsLinkedObjects in eine XML-Datei.

  • Ruft eine Liste der generische Elemente, die mit einer Aufgabe verbunden sind.

  • Löscht die Links zu Web-Objekten.
