Deleting a Slide Step by Step

Now, let’s break down the process of deleting a slide into multiple steps for a clearer understanding.

Step 1: Load the Presentation

// Instantiate a Presentation object that represents a presentation file
using (Presentation pres = new Presentation(dataDir + "YourPresentation.pptx"))
{
    // Your code for slide deletion will go here.
}

In this step, we load the PowerPoint presentation that you want to work with. Replace "Your Document Directory" with the actual directory path and "YourPresentation.pptx" with the name of your presentation file.

Step 2: Access the Slide

// Accessing a slide using its index in the slides collection

Step 3: Remove the Slide

// Removing a slide using its reference
pres.Slides.Remove(slide);

This step involves removing the selected slide from the presentation.

Step 4: Save the Presentation

// Writing the presentation file
pres.Save(dataDir + "modified_out.pptx", Aspose.Slides.Export.SaveFormat.Pptx);
