Sample Presentation: Download the sample presentation, “HelloWorld.pptx,” that we’ll be using in this tutorial. Now, let’s explore the step-by-step guide on how to set slide numbers using Aspose.Slides for .NET.

Import Namespaces

Before you start working with Aspose.Slides, you need to import the necessary namespaces into your project.

using Aspose.Slides.Export;
using Aspose.Slides;

Now, let’s break down each step into more detail:

Step 1: Import Necessary Namespaces

In your .NET project, ensure that you include the following namespaces:

using Aspose.Slides;
using Aspose.Slides.Export;

These namespaces provide the essential classes and methods needed for working with presentations using Aspose.Slides.

Step 2: Load the Presentation

To begin, create an instance of the Presentation class and load your presentation file, in this case, “HelloWorld.pptx.”

string dataDir = "Your Document Directory";
using (Presentation presentation = new Presentation(dataDir + "HelloWorld.pptx"))
{
    // Your code here
}

Step 3: Get and Set Slide Number

Retrieve the current slide number using the FirstSlideNumber property and then set it to your desired value. In the example, we set it to 10.

int firstSlideNumber = presentation.FirstSlideNumber;
presentation.FirstSlideNumber = 10;

Step 4: Save the Modified Presentation

Finally, save the modified presentation with the new slide number.

presentation.Save(dataDir + "Set_Slide_Number_out.pptx", SaveFormat.Pptx);
