Копирование слайда из одной презентации в другую с использованием Open XML SDK ⇐ C#

[Anonymous]

Извините, мой английский < /em> < /p>

Есть код < /p>

Код: Выделить всё

using (var sourceDoc = PresentationDocument.Open(@"d:\source.pptx", false))
{
using (var destDoc = PresentationDocument.Open(@"d:\dest.pptx", true))
{

}
}
< /code>

 я пытаюсь скопировать слайд №2 из sourcedoc < /code> и вставить в destdoc < /code> позиция 4. < /strong> < /p>



Есть статьи с той же названием «Скорее всего», но и на одном из них, но и на одном из них, но и на одном из них. применить это. Я просто смущен. Например: < /p>

uniqueId = GetMaxIdFromChild(destPresPart.Presentation.SlideMasterIdList);
< /code>

Что значит? Время компиляции Скажите ошибку. < /P>



 Обновление #1 < /h2>

Я создал метод для копирования слайда в другую презентацию < /p>

///

var sourcePresentation = sourcePresentationPart.Presentation;

SlideId slideIdSelectedSlide = sourceSlideIdList.ChildElements[slidePosition - 1] as SlideId;
SlidePart sourceSlidePart = sourcePresentationPart.GetPartById(slideIdSelectedSlide.RelationshipId) as SlidePart;

SlidePart destSlidePart = null;

PresentationPart destPresentationPart = null;
using (PresentationDocument destPresentationDocument = PresentationDocument.Open(destPresentationPath, true))

var addedSlidePart = destPresentationDocument.PresentationPart.AddPart(sourceSlidePart);

destSlideIdList = destPresentationDocument.PresentationPart.Presentation.SlideIdList;

destPresentationPart = destPresentationDocument.PresentationPart;

SlideId lastSlideIdInDestPresentation = destSlideIdList.ChildElements.Last() as SlideId;

// Insert the new slide into the slide list after last slide
SlideId addedSlideId = destSlideIdList.InsertAfter(new SlideId(), lastSlideIdInDestPresentation);
addedSlideId.Id = lastSlideIdInDestPresentation.Id++;
addedSlideId.RelationshipId = destPresentationPart.GetIdOfPart(addedSlidePart);

destPresentationPart.Presentation.Save();
}
}
< /code>

Слайд копируется, но без фона.  Как также перемещать фон? < /p>

// Client code
Extensions.CopySlideTo(@"D:\temp\source.pptx", 1, @"D:\temp\dest.pptx");

Теперь, когда я открываю результат (d:\temp\dest.pptx

) См.



Однако, если нажмите remopend em. Как это исправить?>
