 In this video, we will merge PDF files using C-Sharp. To begin, let's copy the sample code and paste it into the Visual Studio Editor. I added the sample code link in the description box below. To extract PDF file, we will use the Bitescout PDF Extractor SDK. You can add a reference to the PDF Extractor SDK DLL in the Solution Explorer. Right-click on Reference and select Add Reference. Look up the PDF Extractor SDK and add. Then, copy the sample files you'd like to merge. We will add our sample file in the Solution Explorer and set the copy to Output Directory to Copy Always. Then, add your registration name and registration key in their corresponding properties accordingly. You can get your license details in the Bitescout dashboard. Then, type the output file name. Now let's run the program. Here's the sample PDF files. And here's the output. For more tutorials, you may visit our YouTube channel and don't forget to hit the Subscribe button.
