Beispiele

Das folgende Beispiel erstellt eine Project -Objekt und verwendet die LoadXml Methode, um Inhalt zum Projekt hinzuzufügen.The following example creates a Project object and uses the LoadXml method to add content to the project. Die BuildItem, BuildItemGroup, und BuildItemGroupCollection Klassen dienen zum Hinzufügen, entfernen und Ändern von Elementen im Projekt.The BuildItem, BuildItemGroup, and BuildItemGroupCollection classes are used to add, remove, and change items in the project.
