C#: Change the Slide Order in a PowerPoint Document
Optimizing the order of slides in a PowerPoint presentation is a simple skill. By rearranging slides, you can refine the logic and flow of your presentation, group related points together, or move slides to more impactful locations. This flexibility enables you to create a cohesive, engaging narrative that captivates your audience.
This article demonstrates how to programmatically change the slide order in a PowerPoint document in C# by using the Spire.Presentation for .NET library.
Install Spire.Presentation for .NET
To begin with, you need to add the DLL files included in the Spire.Presentation for .NET package as references in your .NET project. The DLL files can be either downloaded from this link or installed via NuGet.
PM> Install-Package Spire.Presentation
Change the Slide Order in a PowerPoint Document in C#
To reorder slides in a PowerPoint presentation, create two Presentation objects - one to load the original document and another to create a new document. By copying the slides from the original document to the new one in the desired sequence, you can easily rearrange the slide order.
The steps to rearrange slides in a PowerPoint document using C# are as follows.
- Create a Presentation object.
- Load a PowerPoint document using Presentation.LoadFromFile() method.
- Specify the slide order within an array.
- Create another Presentation object for creating a new presentation.
- Add the slides from the original document to the new presentation in the specified order using Presentation.Slides.Append() method.
- Save the new presentation to a PPTX file using Presentation.SaveToFile() method.
- C#
using Spire.Presentation;
namespace ChangeSlideOrder
{
class Program
{
static void Main(string[] args)
{
// Create a Presentation object
Presentation presentation = new Presentation();
// Load a PowerPoint file
presentation.LoadFromFile("C:\\Users\\Administrator\\Desktop\\input.pptx");
// Specify the new slide order within an array
int[] newSlideOrder = new int[] { 4, 2, 1, 3 };
// Create another Presentation object
Presentation new_presentation = new Presentation();
// Remove the default slide
new_presentation.Slides.RemoveAt(0);
// Iterate through the array
for (int i = 0; i < newSlideOrder.Length; i++)
{
// Add the slides from the original PowerPoint file to the new PowerPoint document in the new order
new_presentation.Slides.Append(presentation.Slides[newSlideOrder[i] - 1]);
}
// Save the new presentation to file
new_presentation.SaveToFile("NewOrder.pptx", FileFormat.Pptx2019);
// Dispose resources
presentation.Dispose();
new_presentation.Dispose();
}
}

Spire.Presentation is a powerful and easy-to-use .NET component, especially designed for developers. Using Spire.Presentation you can generate, modify, convert, render, and print documents without installing Microsoft PowerPoint on your machine. In this document, I will introduce you how to create PowerPoint file and save it to stream. I also introduce you how to load PowerPoint file from stream. Check it below.
Create PowerPoint file and save it to Stream
Step 1: Create Presentation instance.
Presentation presentation = new Presentation();
Step 2: Set background image.
string ImageFile = "bg.png"; RectangleF rect = new RectangleF(0, 0, presentation.SlideSize.Size.Width, presentation.SlideSize.Size.Height); presentation.Slides[0].Shapes.AppendEmbedImage(ShapeType.Rectangle, ImageFile, rect); presentation.Slides[0].Shapes[0].Line.FillFormat.SolidFillColor.Color = Color.FloralWhite;
Step 3: Add text to PowerPoint document.
IAutoShape shape = presentation.Slides[0].Shapes.AppendShape(ShapeType.Rectangle, new RectangleF(50, 70, 450, 150)); shape.Fill.FillType = FillFormatType.None; shape.ShapeStyle.LineColor.Color = Color.White; //add text to shape shape.TextFrame.Text = "This demo shows how to Create PowerPoint file and save it to Stream."; shape.TextFrame.Paragraphs[0].TextRanges[0].Fill.FillType = FillFormatType.Solid; shape.TextFrame.Paragraphs[0].TextRanges[0].Fill.SolidColor.Color = Color.Black;
Step 4: Save document to stream.

How to Remove Slides from a Presentation
Sometimes, we may need to delete specific slide in a PowerPoint presentation due to any reason. This section will illustrate that how we can accomplish that task using Spire.Presentation for .NET.
As a matter of fact, it is quite easy and convenient to remove slides by only one line of core code if you have Spire.Presentation.Dll installed as a reference in your .NET project assemblies. Here is the method:
Step 1: Create an instance of presentation class and load PPT documents
Presentation presentation = new Presentation();
presentation.LoadFromFile("sample.pptx");
Step 2: Remove the second slide from the presentation by using its index position
presentation.Slides.RemoveAt(1);
Step 3: Save and review
presentation.SaveToFile("result.pptx",FileFormat.Pptx2010);
System.Diagnostics.Process.Start("result.pptx");
Original layout:
