Watch out for escape characters.

You have to be aware of the escape characters when you parse a file  character by character.  For instance if you try to read a file that contains “C:\bigFile.txt” you’ll get back “C:igFile.txt” or something like this.

If you don’t believe me, try it yourselves.

   1: public void ParseString()

   2: {

   3:     string text = "C:\bigFile.txt";

   4:     string newText = string.Empty;

   5:     foreach (char c in text)

   6:     {

   7:         newText += c;

   8:     }

   9:     Console.WriteLine(newText);

  10: }

Below I provided a table of escape character for you and myself to reference later.
