PowerPoint .NET Component (Code Example)
Delivering presentations is still a key part of how businesses share information—whether it’s for reports, pitch decks, client proposals, or training slides. As a .NET developer, you may eventually be tasked with generating or modifying PowerPoint presentations programmatically. This is where IronPPT, a powerful PowerPoint .NET library, comes in.
IronPPT is a robust .NET library designed specifically for working with PowerPoint (PPTX) files in C# and VB.NET. It offers a powerful alternative to Microsoft Office automation, allowing you to create, edit, convert, and extract content from slides—all without needing to require Microsoft PowerPoint installed.
In this guide, you’ll learn how IronPPT works, how to integrate it into your .NET applications, and where it excels in real-world use cases. Whether you’re building a reporting tool, automating the creation of PowerPoint documents, or looking for a tool to edit your existing presentations, IronPPT helps you do it cleanly and efficiently.

Let’s begin with a closer look at what IronPPT is and why it’s worth considering in your .NET projects:
What Is IronPPT?
IronPPT is a .NET PowerPoint library from Iron Software that allows developers to programmatically create and edit PowerPoint slide files without requiring Office or PowerPoint to be installed on the machine. It’s designed for use in web, desktop, and server environments, including Visual Studio solutions.
Why Use IronPPT in .NET Applications?
For .NET developers working on enterprise applications, reports, dashboards, or document automation, IronPPT offers a reliable and scalable solution to generate and manipulate PowerPoint elements dynamically. It’s ideal for cloud platforms like Azure or for any environment where Microsoft Office Interop isn’t practical or performant.
Getting Started with IronPPT in .NET
Before diving into code, here’s how to get IronPPT set up and ready to use:
Install via NuGet Package Manager
The easiest way to add IronPPT to your project is via NuGet. Just run:
Install-Package IronPPT
Install-Package IronPPT
'INSTANT VB TODO TASK: The following line uses invalid syntax:
'Install-Package IronPPT
This installs all required dependencies and makes the library immediately available to your .NET application.
Supported Frameworks and Environments
IronPPT supports:
- .NET Framework 4.6.2 and later
- .NET Core 3.1
- .NET 5, 6, 7, and 8
- Compatible with Windows, Linux (via .NET Core), and Azure App Services
You can use it in desktop (WinForms/WPF), web (ASP.NET), or background services.
Core Capabilities of IronPPT for Developers
IronPPT includes a variety of features that make working with multiple PowerPoint presentations and editing PowerPoint more flexible and scalable in C#:
Programmatic Slide Creation
Easily create new slides with titles, subtitles, and layout configurations. This is ideal for auto-generating visual representation of content based on business logic or database input.
Content Editing and Layout Control
Modify existing slides by updating text, inserting pictures, or changing background colors. You can also rearrange slide order, duplicate slides, or remove them entirely.
Add Images and Shapes
Programmatically insert JPEG, PNG, logos, shapes, or chart images into slides—perfect for dynamic data visualization, rich media content for reporting.
Practical Code Examples with IronPPT
Now let’s look at some real code to see how these features work in practice:
Creating a PowerPoint Document from Scratch
using IronPPT;
var ppt = new PresentationDocument();
// Add Text to the new presentation
ppt.Slides[0].TextBoxes[0].AddText("Welcome to IronPPT");
ppt.Slides[0].TextBoxes[1].AddText("This slide was generated using IronPPT!");
// Save the presentation
ppt.Save("new_presentation.pptx");
using IronPPT;
var ppt = new PresentationDocument();
// Add Text to the new presentation
ppt.Slides[0].TextBoxes[0].AddText("Welcome to IronPPT");
ppt.Slides[0].TextBoxes[1].AddText("This slide was generated using IronPPT!");
// Save the presentation
ppt.Save("new_presentation.pptx");
Imports IronPPT
Private ppt = New PresentationDocument()
' Add Text to the new presentation
ppt.Slides(0).TextBoxes(0).AddText("Welcome to IronPPT")
ppt.Slides(0).TextBoxes(1).AddText("This slide was generated using IronPPT!")
' Save the presentation
ppt.Save("new_presentation.pptx")

Editing an Existing PowerPoint File
using IronPPT;
// Load the existing pptx file
var ppt = new PresentationDocument("new_presentation.pptx");
// Edit the existing text
ppt.Slides[0].TextBoxes[0].Texts[0].Text = "Hello World!";
ppt.Save("updated.pptx");
using IronPPT;
// Load the existing pptx file
var ppt = new PresentationDocument("new_presentation.pptx");
// Edit the existing text
ppt.Slides[0].TextBoxes[0].Texts[0].Text = "Hello World!";
ppt.Save("updated.pptx");
Imports IronPPT
' Load the existing pptx file
Private ppt = New PresentationDocument("new_presentation.pptx")
' Edit the existing text
Private ppt.Slides(0).TextBoxes(0).Texts(0).Text = "Hello World!"
ppt.Save("updated.pptx")

Insert an Image into a Slide
using IronPPT;
using IronPPT.Models;
var ppt = new PresentationDocument("updated.pptx");
Image img = new Image();
img.LoadFromFile("IronPPT.png");
var newImg = ppt.AddImage(img, 0);
newImg.Position = (150, 50);
newImg.Width = 400;
newImg.Height = 150;
ppt.Save("image.pptx");
using IronPPT;
using IronPPT.Models;
var ppt = new PresentationDocument("updated.pptx");
Image img = new Image();
img.LoadFromFile("IronPPT.png");
var newImg = ppt.AddImage(img, 0);
newImg.Position = (150, 50);
newImg.Width = 400;
newImg.Height = 150;
ppt.Save("image.pptx");
Imports IronPPT
Imports IronPPT.Models
Private ppt = New PresentationDocument("updated.pptx")
Private img As New Image()
img.LoadFromFile("IronPPT.png")
Dim newImg = ppt.AddImage(img, 0)
newImg.Position = (150, 50)
newImg.Width = 400
newImg.Height = 150
ppt.Save("image.pptx")

Add and Reorder Slides
First, we need to add some slides to our presentation, this is done with code such as the following code example.
using IronPPT;
using IronPPT.Models;
var ppt = new PresentationDocument("updated.pptx");
Slide slide = new Slide();
slide.AddText("Slide Two");
ppt.AddSlide(slide);
ppt.Save("updated.pptx");
using IronPPT;
using IronPPT.Models;
var ppt = new PresentationDocument("updated.pptx");
Slide slide = new Slide();
slide.AddText("Slide Two");
ppt.AddSlide(slide);
ppt.Save("updated.pptx");
Imports IronPPT
Imports IronPPT.Models
Private ppt = New PresentationDocument("updated.pptx")
Private slide As New Slide()
slide.AddText("Slide Two")
ppt.AddSlide(slide)
ppt.Save("updated.pptx")

Now we have a presentation with multiple slides, now we can easily reorder these with this code:
using IronPPT;
IronPPT.License.LicenseKey = "IRONSUITE.WRITERS.21046-907F5E67CC-AHYQW6L-RCHLPMRJMU4G-SET72XAF2JNY-LQK45E5JPLGW-XOLPVBEBLHV7-2LHKZRWUZWMO-5LNIZSPF4BM6-UHUH4R-T4MMJ4MEIYSQEA-DEPLOYMENT.TRIAL-LDG2MK.TRIAL.EXPIRES.16.NOV.2025";
var ppt = new PresentationDocument("updated.pptx");
ppt.Slides[2].Index = 1;
ppt.Save("updated.pptx");
using IronPPT;
IronPPT.License.LicenseKey = "IRONSUITE.WRITERS.21046-907F5E67CC-AHYQW6L-RCHLPMRJMU4G-SET72XAF2JNY-LQK45E5JPLGW-XOLPVBEBLHV7-2LHKZRWUZWMO-5LNIZSPF4BM6-UHUH4R-T4MMJ4MEIYSQEA-DEPLOYMENT.TRIAL-LDG2MK.TRIAL.EXPIRES.16.NOV.2025";
var ppt = new PresentationDocument("updated.pptx");
ppt.Slides[2].Index = 1;
ppt.Save("updated.pptx");
Imports IronPPT
IronPPT.License.LicenseKey = "IRONSUITE.WRITERS.21046-907F5E67CC-AHYQW6L-RCHLPMRJMU4G-SET72XAF2JNY-LQK45E5JPLGW-XOLPVBEBLHV7-2LHKZRWUZWMO-5LNIZSPF4BM6-UHUH4R-T4MMJ4MEIYSQEA-DEPLOYMENT.TRIAL-LDG2MK.TRIAL.EXPIRES.16.NOV.2025"
Dim ppt = New PresentationDocument("updated.pptx")
ppt.Slides(2).Index = 1
ppt.Save("updated.pptx")

Now the slide with the "Slide Two" text has been reordered into the proper position as the second slide in our presentation.
