C# 使用 iTextSharp 将 PDF 转换成 TXT 文本

             var pdfReader = new PdfReader("xxx.pdf");
 
             StreamWriter output = new StreamWriter(new FileStream("处理结果.txt", FileMode.Create));
 
             int pageCount = pdfReader.NumberOfPages;
             for (int pg = ; pg <= pageCount; pg++)
             {
                 ITextExtractionStrategy strategy = new SimpleTextExtractionStrategy();
                 var value = PdfTextExtractor.GetTextFromPage(pdfReader, pg, strategy);
                 value = value.Replace(" ", "");
                 Console.WriteLine(value);
                 output.Write(value);
             }
 
             output.Flush();
             output.Close();
             Console.Write("处理完毕");
             Console.ReadLine();

该方法读出的汉字不会乱码。
