如何在ppt中为特定幻灯片添加Notes？ [英] How to add Notes to a particular slide in a ppt?

问题描述

目前我有一项任务是使用openxml将自定义注释插入到ppt的特定幻灯片中。引用此链接。我正在尝试为幻灯片添加注释但是我收到以下错误。

Currently I have a task that insert custom note to a particular slide of a ppt using openxml. from referencing this link. I am trying to add note to a slide but I am getting the following Error.

   Error Message :Only one instance of the type is allowed for this parent.
Stack Trace:
at DocumentFormat.OpenXml.Packaging.OpenXmlPartContainer.InitPart[T](T newPart, String contentType, String id)
   at DocumentFormat.OpenXml.Packaging.OpenXmlPartContainer.InitPart[T](T newPart, String contentType)
   at DocumentFormat.OpenXml.Packaging.OpenXmlPartContainer.AddNewPartInternal[T]()

   at AddNoteToPPT.Program.AddNote(String docName, Int32 index) in d:\Projects\Task\Project\AddNoteToPPT\AddNoteToPPT\Program.cs:line 45

这是我的工作副本

Here is my working copy

NotesSlidePart notesSlidePart1 = slide.AddNewPart<NotesSlidePart>();
NotesSlide notesSlide = new NotesSlide(
new CommonSlideData(new ShapeTree(
  new P.NonVisualGroupShapeProperties(
  new P.NonVisualDrawingProperties() { Id = (UInt32Value)1U, Name = "" },
  new P.NonVisualGroupShapeDrawingProperties(),
  new ApplicationNonVisualDrawingProperties()),
  new GroupShapeProperties(new TransformGroup()),
  new P.Shape(
  new P.NonVisualShapeProperties(
	new P.NonVisualDrawingProperties() { Id = (UInt32Value)2U, Name = "" },
	new P.NonVisualShapeDrawingProperties(new ShapeLocks() { NoGrouping = true }),
	new ApplicationNonVisualDrawingProperties(new PlaceholderShape())),
  new P.ShapeProperties(),
  new P.TextBody(
	new BodyProperties(),
	new ListStyle(),
	new Paragraph(new EndParagraphRunProperties()))))),
new ColorMapOverride(new MasterColorMapping()));
notesSlidePart1.NotesSlide = notesSlide;

使用此代码我可以获得现有Note的内容。

using this code I am able to get the content of existing Note.

slide.NotesSlidePart.SlidePart.NotesSlidePart.NotesSlide.InnerText
