>>Using the char[] approach results in a string being written to the array for anything between a LF and CR (which if fine) but also for anything between CR and LF which, in the scenario, is an empty string. If you didn't have any genuinely empty strings between a LF and CR then using the StringSplitOptions.RemoveEmptyEntries would be fine but that wasn't the case.....

Just

oLine = tcString.Split(lcDelimiter, StringSplitOptions.None)
