Not sure if this is exactly what you're looking for, but it's how I've been setting the slide size.

this.Application.ActivePresentation.PageSetup.SlideHeight = <your slide height>;
this.Application.ActivePresentation.PageSetup.SlideWidth = <your slide width>;

Allows you to set the width and height of the slide in points, not pixels. You can use the below to convert pixels to points

private int PixelsToPoints(int pixels)
{
     return pixels * 72 / 96;
}

Try running your code. the error msg is " Invalid request. There is no active presentation." why?? – doo0301 Feb 22 '17 at 14:04
Have you tried the code after creating a presentation? I'm running it when a presentation has been created, and a slide is visible. It then adjusts the size of the slide, and subsequent slides – Sandwich Feb 22 '17 at 14:58
@Sandwich Thanks for your help, I found the problem, it is this line of code can not achieve the desired effect, I changed the other way – doo0301 Feb 22 '17 at 15:03
@Sandwich Could you please mention where the "72" value comes from? What's the point of it? – Nahuel Ianni Jun 12 '17 at 11:49

now,this is right code:

        PowerPoint.Application pptApp = new PowerPoint.Application();
        MyPres = pptApp.Presentations.Add(MsoTriState.msoTrue);
        MyPres.PageSetup.SlideWidth = <slide width>;
        MyPres.PageSetup.SlideHeight = <slide height >;

This line of code have bug?, I'm not sure !!

        MyPres.PageSetup.SlideSize = PowerPoint.PpSlideSizeType.ppSlideSizeOnScreen16x9;
