I have some log files I need to process via VB.NET and C# based applications.
I read the entire contents of each file individually into a string variable
using the StreamReader class (.ReadToEnd). I want to split the lines up from
each file and add the lines to an an ArrayList (via AddRange), but for some
reason I cannot come up with a way to split the lines correctly.

Can anyone please provide a method using string conversions or Regex to
alter the string content so I can split the string into lines correctly?

Thanks,

Matt

Mesterac,

You can split a file directly into an array with the different split
methods.

I hope this helps,

Correct...use split either via string method or Regex, but split by what?
UNIX formatted files do not end in equivalent of vbCrLf. I cannot determine
the correct character or sequence of characters which indicate end of line.

DOS uses <CR><LF> Unix just uses <LF> - so you should be able to split
on <LF>.

Can you look at the file in a hex editor to confirm?

UNIX formatted file ends in hex 0A. Windows formatted file ends in hex 0D
followed by 0A.

That's correct <LF> and <CR><LF> as I said. So can you split on <LF>?
