In this how-to tutorial, we walk you through the step-by-step process to compare PowerPoint files using C#. This guide also includes the instructions for configuring the document comparison package and how to develop the functionality to compare two PowerPoint files in C#. Here are the detailed instructions for comparing PowerPoint files as well as a working example for it.

To compare PowerPoint documents using C#, you need to follow the above instructions in a sequence. You can start the document comparison functionality by installing the required package and adding the necessary namespace in the code.

In the preceding snippet, we have created the functionality to compare two PPTX files for differences in C#. We have just used the steps defined in previous sections and completed the functionality by consuming a few API calls of the document comparison package. Further, this code can be executed on any operating system like MS Windows, Linux, and Mac OS.
