Hi, if you do not mind using a third-party library, you cloud try Spire.Presentation for .NET to do the conversion through the following code snippet.

using Spire.Presentation;

namespace PPTXtoPDF
{
    class Program
    {
        static void Main(string[] args)
        {
            //create a Presnetation object
            Presentation presentation = new Presentation();
            //load powerpoint file 
            presentation.LoadFromFile("test.pptx");
            //save to pdf
            presentation.SaveToFile("ToPdf.pdf", FileFormat.PDF);
        }
    }
}
