How to Add a Numbered List to Notes in PowerPoint in C#

When creating a speaker notes in a presentation slide, you can add more than one item or paragraph in notes and display them within a numbered list. In this tutorial, we’ll show you how to add a numbered list to notes using Spire.Presentation in C#.

Step 1: Initialize an instance of Presentation and get the first slide.

Presentation ppt = new Presentation();
ISlide slide = ppt.Slides[0];

Step 2: Add a new notes slide in the specified slide.

NotesSlide notesSlide = slide.AddNotesSlide();

Step 3: Add a new paragraph with the text to speaker notes.

TextParagraph paragraph = new TextParagraph();
paragraph.Text = "Tips for making effective presentations:";
notesSlide.NotesTextFrame.Paragraphs.Append(paragraph);

Step 4: Add another paragraph with the text to notes, set the bullet type of the paragraph as numbered, and set the numbered style as Arabic number following by period.

paragraph = new TextParagraph();
paragraph.Text = "Use the slide master feature to create a consistent and simple design template.";
notesSlide.NotesTextFrame.Paragraphs.Append(paragraph);
notesSlide.NotesTextFrame.Paragraphs[1].BulletType = TextBulletType.Numbered;
notesSlide.NotesTextFrame.Paragraphs[1].BulletStyle = NumberedBulletStyle.BulletArabicPeriod;

Step 5: Repeat step 4 to add many more numbered paragraphs to notes.

paragraph = new TextParagraph();
paragraph.Text = "Simplify and limit the number of words on each screen.";
notesSlide.NotesTextFrame.Paragraphs.Append(paragraph);
notesSlide.NotesTextFrame.Paragraphs[2].BulletType = TextBulletType.Numbered;
notesSlide.NotesTextFrame.Paragraphs[2].BulletStyle = NumberedBulletStyle.BulletArabicPeriod;

paragraph = new TextParagraph();
paragraph.Text = "Use contrasting colors for text and background.";
notesSlide.NotesTextFrame.Paragraphs.Append(paragraph);
notesSlide.NotesTextFrame.Paragraphs[3].BulletType = TextBulletType.Numbered;
notesSlide.NotesTextFrame.Paragraphs[3].BulletStyle = NumberedBulletStyle.BulletArabicPeriod;

Step 6: Save the file.

ppt.SaveToFile("Output.pptx", FileFormat.Pptx2013);

Output:
