StreamReader not reading the whole file

Hi!

I am trying to read a file with streamreader in unity 5, but it only reads 136 lines even though the file has 52116 lines.

Here is the code:

 import System.IO;
 var fileName = "fingerprint.txt";

 function Start () {
   var sr = new StreamReader(Application.dataPath + "/FingerPrintKeysRead/" + fileName);
   var fileContents = sr.ReadToEnd();
   sr.Close();
 
   var lines = fileContents.Split("\n"[0]);
   for (line in lines) {
      print (line);
   }
  }

What am I doing wrong? Help would be much appriciated. Thanks!

(ps. each line contains a byte so maybe Streamreader is not the best way of doing it)
