Loading a PowerPoint Presentation

To erase slides from a PowerPoint presentation, we first need to load the presentation. Here’s how you can do it:

using Aspose.Slides;

// Load the PowerPoint presentation
string presentationPath = "path_to_your_presentation.pptx";
using (Presentation presentation = new Presentation(presentationPath))
{

}

Erasing Slides by Sequential Index

Now, let’s write the code to erase slides by their sequential index:

// Assuming you want to erase slide at index 2
int slideIndexToRemove = 1; // Slide indices are 0-based

// Remove the slide at the specified index
presentation.Slides.RemoveAt(slideIndexToRemove);

Saving the Modified Presentation

Once you’ve erased the desired slides, you need to save the modified presentation:

// Save the modified presentation
string outputPath = "path_to_output.pptx";
presentation.Save(outputPath, SaveFormat.Pptx);
