What makes you think that is C# (It isn't it's VB.Net)?
In any case try this.
1. Make sure you can see the pptx suffix on your file icon. If you can't google for show file extensions in windows and change the settings. Do everything below on a COPY
2. Add .zip to the end so it reads something.pptx.zip
Open the zip file and look in the PPT / Media file to see if you can find the image.
Even easier Google for 7Zip and install (free) You can right click a pptx and create a new zip archive which you can open in the same way.
