问题 Is it possible to return byte[] using the GhostscriptProcessor? For example: public static byte[] ConvertToPDFA(byte[] pdfData) { GhostscriptProcessor gsproc = new GhostscriptProcessor(Properties.Resources.gsdll32); //return byte[] from the created PDF/A The method StartProcessing is a void method, but is there any alternative thet can create a PDF/A from a PDF File and return a byte[] from its content? 回答1: It's possible: public class PipedOutputSample { public void Start() { string
