如何读取加密文本文件中的行数？

Question

So i have this encrypt text files program (which works as desired), the problem is that i need to display this result on a MessageBox:

The numbers of lines readed BEFORE encrypting and AFTER the files is encrypted....

the line-counter for the lines readed before encrypting already works WITH the same algorithm

Ej. 'X' numbers of lines readed 'Y' numbers of line are encrypted.

i have this simple algorithm to read the encrypted file:

    public long CountlLines(string a)
    {
        long count = 0;
        string line;

        FileStream FS = new FileStream(a, FileMode.Open, FileAccess.Read);
        StreamReader Reader = new StreamReader(FS);

        while (Reader.EndOfStream == false)
        {
            line = Reader.ReadLine();
            count++;
        }


        Reader.Close();
        return count;
    }

i got this 159 lines files that, when decrypted, produces 11 lines of encrypted code (opened on notepad), but with this algorithm i got:

Ej. '159' numbers of lines readed '1' numbers of line are encrypted.

The encryption method is AES, with a 128-bits key...(in case of...). Am i doing something wrong? or is there some kind of specific method or 'way' to read encrypted text? Thanks.

Answer 1

Your encrypted file contains no newline markers. Thus when your "Reader.ReadLine()" executes, it does what you asked it to. It reads the lines until it comes to a newline, which there arent any of, because you have encrypted them all. Its all one line now.

Assuming of course you have encrypted the entire contents, and not line by line ;)
