Prerequisites

Before we dive into the code, make sure you have the following prerequisites in place:

1. Visual Studio or any other compatible .NET development environment.
2. Aspose.Slides for .NET library. You can download it from here.

Step 1: Create a New Project

Open your preferred development environment and create a new .NET project. Choose the appropriate project type based on your needs, such as Console Application or Windows Forms Application.

Step 2: Add References

Add references to the Aspose.Slides for .NET library in your project. To do this, follow these steps:

1. Right-click on your project in the Solution Explorer.
2. Select “Manage NuGet Packages…”
3. Search for “Aspose.Slides” and install the appropriate package.

Step 3: Initialize Presentation

In this step, you’ll initialize a presentation object and load the existing PowerPoint presentation file where you want to insert additional slides.

using Aspose.Slides;

// Load the existing presentation
using Presentation presentation = new Presentation("path_to_existing_presentation.pptx");

Replace "path_to_existing_presentation.pptx" with the actual path to your existing presentation file.

Step 4: Create New Slides

Next, let’s create new slides that you want to insert into the presentation. You can customize the content and layout of these slides according to your requirements.

// Create new slides
Slide slide1 = presentation.Slides.AddEmptySlide(presentation.SlideSize);
Slide slide2 = presentation.Slides.AddEmptySlide(presentation.SlideSize);

// Customize the content of the slides
slide1.Shapes.AddTitle().Text = "New Slide 1";
slide2.Shapes.AddTitle().Text = "New Slide 2";

Step 5: Insert Slides

Now that you’ve created the new slides, you can insert them into the desired position in the presentation.

// Insert slides at a specific position
int insertionIndex = 2; // Index where you want to insert the new slides
presentation.Slides.InsertClone(insertionIndex, slide1);
presentation.Slides.InsertClone(insertionIndex + 1, slide2);

Adjust the insertionIndex variable to specify the position where you want to insert the new slides.

Step 6: Save Presentation

After inserting the additional slides, you should save the modified presentation.

// Save the modified presentation
presentation.Save("path_to_modified_presentation.pptx", SaveFormat.Pptx);

Replace "path_to_modified_presentation.pptx" with the desired path and filename for the modified presentation.
