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.

Let me know if I miss anything.
