Java高手看过来（在下小小C#程序员一名）

Question

下面这段运用xpdf的代码如何转化为c#
高手们要不吝赐教啊，小弟在这里先谢过了（就50分吧）String PATH_TO_XPDF="C:\\xpdf\\pdftotext.exe";               String filename="c:\\test.pdf";                                  int Begin = 100;                 int End = 300;                                  String strResponse = "";                                String[] cmd = new String[]                     { PATH_TO_XPDF,                             "-cfg", "xpdfrc", "-q", filename, "-"};               Process p = Runtime.getRuntime().exec(cmd);               BufferedInputStream bis = new BufferedInputStream(p.getInputStream());               InputStreamReader reader = new InputStreamReader(bis, "UTF-8");                                   if(Begin > 0)                 {                      // 跳过Begin个字符                      reader.skip(Begin);                 }                                                    // 本次要读取的字符数                 int nLengthRead = End - Begin;                 if(nLengthRead > 0)                 {                      // 准备好缓冲区                     char [] buf = new char[nLengthRead];                      // 输出到缓冲区                     int nLengthWriteToBuffer = reader.read(buf);                     reader.close();                                            // nLengthWriteToBuffer就是当前读取到缓冲区的字符数                      if(nLengthWriteToBuffer > 0)                      {                            // 只有nLengthWriteToBuffer大于0，才说明文档有内容                            strResponse = new String(buf);                      }                      else                      {                            // 否则可能是到了文档结尾                            strResponse = "PDF_EOF_OF_DOC";                      }                 }                                System.out.println("\t\r\n" + strResponse);

Answer 1

c#也有对应的类运行exe,找找就可以,不难.

Answer 2

找个 C# 读取文件， google  一下，特别多

Answer 3

是不是java高手都不懂c#？还是这年头牛人都不爱帮忙？

Answer 4

没有测试过
 string PATH_TO_XPDF = @"C:\xpdf\pdftotext.exe";            string filename = @"c:\test.pdf";            int Begin = 100;            int End = 300;            string strResponse = "";            ProcessStartInfo ps = new ProcessStartInfo(PATH_TO_XPDF);
            ps.Arguments = " -cfg xpdfrc -q " + filename + "-";//设置命令参数
            ps.CreateNoWindow = true;
            ps.RedirectStandardOutput = true;
            ps.RedirectStandardInput = true;
            ps.UseShellExecute = false;
            Process p = Process.Start(ps);
            StreamReader reader = p.StandardOutput;//截取输出流
            
            if (Begin > 0)
            {                
                reader.BaseStream.Seek(Begin, SeekOrigin.Begin);
            }            int nLengthRead = End - Begin;            if (nLengthRead > 0)
            {
                // 准备好缓冲区
                char[] buf = new char[nLengthRead];
                // 输出到缓冲区
                int nLengthWriteToBuffer = reader.Read();
                reader.Close();
                // nLengthWriteToBuffer就是当前读取到缓冲区的字符数
                if (nLengthWriteToBuffer > 0)
                {
                    // 只有nLengthWriteToBuffer大于0，才说明文档有内容
                    strResponse = new String(buf);
                }
                else
                {
                    // 否则可能是到了文档结尾
                    strResponse = "PDF_EOF_OF_DOC";
                }
            }            Console.WriteLine("\t\r\n" + strResponse);

Answer 5

你这也算c#程序员？读不懂这么简单的java 代码！
