OpenXML-為演示文稿中的幻燈片設置幻燈片布局

Question

這是我用來創建演示文稿的代碼。

我在這里嘗試的是創建幻燈片並將形狀插入其中並將幻燈片附加到已創建的演示文稿中。 很好

我的問題是我如何設置插入幻燈片的布局。 我的意思是這里的幻燈片布局是

slideLayoutpart.SlideLayout = new SlideLayout() {
    Type = SlideLayoutValues.VerticalTitleAndText
};

我想將此布局設置為我的幻燈片。

我曾經在這里使用slidelayout

Slide slide = new Slide(new CommonSlideData(new ShapeTree()));

uint drawingObjectId = 1;

// Construct the slide content.            
// Specify the non-visual properties of the new slide.
NonVisualGroupShapeProperties nonVisualProperties = slide.CommonSlideData.ShapeTree.AppendChild(new NonVisualGroupShapeProperties());
nonVisualProperties.NonVisualDrawingProperties = new NonVisualDrawingProperties() { Id = 1, Name = "" };
nonVisualProperties.NonVisualGroupShapeDrawingProperties = new NonVisualGroupShapeDrawingProperties();
nonVisualProperties.ApplicationNonVisualDrawingProperties = new ApplicationNonVisualDrawingProperties();

// Specify the group shape properties of the new slide.
slide.CommonSlideData.ShapeTree.AppendChild(new GroupShapeProperties());

// Declare and instantiate the title shape of the new slide. TITLE SHAPE
Shape titleShape = slide.CommonSlideData.ShapeTree.AppendChild(new Shape());
drawingObjectId++;

// Specify the required shape properties for the title shape. 
NonVisualShapeProperties nonVisualShapeProperties2;
ShapeProperties shapeProperties2;

CreateVisualProperties(out nonVisualShapeProperties2, out shapeProperties2,
    PlaceholderValues.Title, drawingObjectId);

// Specify the text of the title shape.
TextBody titletextBody = CreateContent(slideTitle, PlaceholderValues.Title);

titleShape.Append(nonVisualShapeProperties2);
titleShape.Append(shapeProperties2);
titleShape.Append(titletextBody);


// Save the new slide part.
slide.Save(slidePart);

#region Slide Poistioning

// The slide ID list should not be null.
SlideIdList slideIdList = presentationPart.Presentation.SlideIdList;

// Find the highest slide ID in the current list.
uint maxSlideId = 1;
SlideId prevSlideId = null;


foreach (SlideId slideId in slideIdList.ChildElements)
{

    if (slideId.Id > maxSlideId)
    {
        maxSlideId = slideId.Id;
    }

    position--;
    if (position == 0)
    {
        prevSlideId = slideId;
    }

}

maxSlideId++;

// Get the ID of the previous slide.
SlidePart lastSlidePart;

if (prevSlideId != null)
{
    //Changed to set first thing as layout
    // lastSlidePart = (SlidePart)presentationPart.GetPartById(((SlideId)(slideIdList.ChildElements[0])).RelationshipId);
    lastSlidePart = (SlidePart)presentationPart.GetPartById(prevSlideId.RelationshipId);
}
else
{
    lastSlidePart = (SlidePart)presentationPart.GetPartById(((SlideId)(slideIdList.ChildElements[0])).RelationshipId);
}

// Use the same slide LAYOUT HERE as that of the previous slide.
if (null != lastSlidePart.SlideLayoutPart)
{
    SlideLayoutPart slideLayoutpartNew = lastSlidePart.SlideLayoutPart;
    slideLayoutpartNew.AddNewPart<SlideMasterPart>();
    slideLayoutpartNew.SlideLayout = new SlideLayout() { Type = SlideLayoutValues.VerticalTitleAndText };
    slidePart.AddPart(slideLayoutpartNew);

    slidePart.AddPart(slideLayoutPart);

    //When i try to set lastslidelayout it works fine.
    //slidePart.AddPart(lastSlidePart.SlideLayoutPart);
}

// Insert the new slide into the slide list after the previous slide.
SlideId newSlideId = slideIdList.InsertAfter(new SlideId(), prevSlideId);
newSlideId.Id = maxSlideId;
newSlideId.RelationshipId = presentationPart.GetIdOfPart(slidePart);
#endregion

// Save the modified presentation.
presentationPart.Presentation.Save();

我想通了，如何設置布局

 string layoutName = "Title and Content";

        // Get SlideMasterPart and SlideLayoutPart from the existing Presentation Part
        SlideMasterPart slideMasterPart = presentationPart.SlideMasterParts.First();
        SlideLayoutPart slideLayoutPart = slideMasterPart.SlideLayoutParts.SingleOrDefault
            (sl => sl.SlideLayout.CommonSlideData.Name.Value.Equals(layoutName, StringComparison.OrdinalIgnoreCase));
        if (slideLayoutPart == null)
        {
            throw new Exception("The slide layout " + layoutName + " is not found");
        }

        slidePart.AddPart<SlideLayoutPart>(slideLayoutPart);

我在這里將布局添加到slidepart並將保存演示文稿
