PowerPoint to JPEG Convertor

A relatively good template is required for the graduation project defense recently. Although I have collected thousands of templates, the results of automatic PPT thumbnails are too poor. You need to manually open the templates to view them, very troublesome. Today, I used C # To write a small Program Converts PowerPoint to JPEG and can be used to quickly query PPT, pptx, and pot content. Simple, convenient, and practical. Code A little messy.
Install Office 2007 before that.
PS: the first version of the program forgot P. Close (), that is, closing the current slide, resulting in the final memory usage of 1.5 GB, full running speed, super cold ~~~
