The sample below shows how to test if a PDF document is compatible with the PDF/A standard in C# using PDF Extractor SDK.

PDF-A Compatibility Test in C#

using System;
using Bytescout.PDFExtractor;

namespace PDFATest
	class Program
		static void Main(string[] args)
			// Create Bytescout.PDFExtractor.PDFAValidator instance
			PDFAValidator validator = new PDFAValidator();
			validator.RegistrationName ="demo";
			validator.RegistrationKey = "demo";

			// Load sample PDF document
			if (validator.IsPDFA)
				Console.WriteLine("This file conforms to the PDF/A standard");
				Console.WriteLine("This file doesn't conform to the PDF/A standard. Check .ValidationErros for the list of errors");

			Console.WriteLine("Press any key to continue...");
