如何解决此异常“ Tesseract引擎尚未初始化”

Question

 OCRProcessor processor = new OCRProcessor(@"\App_Data\Tesseract binaries\");
 PdfLoadedDocument loadedDocument = new PdfLoadedDocument("fed excel.pdf");
 processor.Settings.Language = "eng";
 processor.PerformOCR(loadedDocument, @"\App_Data\Tessdata\");
 loadedDocument.Save("Sample.pdf");
 loadedDocument.Close(true);

我正在获取System.exeception
