Adding string elements to List

Question

Hello guys. I have an recursion function which opens me all directories from the path parameter, and gets all .pdf files. Instead of printing each file to the Console, I want to add it to a List<string> which is one of the function parameters.

This is my code:

        private static void GetAllFilesFrom(string path, string extension)

        {

            try

            {

                if ((File.GetAttributes(path) & FileAttributes.ReparsePoint) != FileAttributes.ReparsePoint)

                {

                    foreach (string folder in Directory.GetDirectories(path))

                    {

                        foreach (string file in Directory.GetFiles(folder, extension))

                        {

                            Console.WriteLine(file);

                        }

                        GetAllFilesFrom(folder, extension);

                    }

                }

            }

            catch (UnauthorizedAccessException) { }

        }
