The code assumes that there exist at least four lines of text in the file.Are you sure this is the case?
I would suggest you write your code to first assert that the lines array actually contains as many lines as you expect. It's entirely possible that the file does not - or that the line breaks are non-standard and therefore not recognized by ReadAllLines().
As a general rule, when parsing or splitting the contents of a file that you expect to have a certain format, you should write your code in a way that asserts your expectations. Otherwise, it can become quite difficult to diagnose what occurred when things go wrong.
Another place in your code you may want to re-examine, are lines like:
Here, again, you assume that the line has a certain structure, and then you access the second index in the result using the indexing operator [] - which could also be a potential source of the error.
@LBushkin raises one of the main problems with the code.
The second problem is that it assumes that each line contains atleast one '~'(you keep accessing .split(ca,2)[1]) , which does not seem to be the case in the sample txt file you posted.I suggest replacing all code of the form :
