I am parsing a very large file of records (one per line, each of varying length), and I'd like to keep track of the number of bytes I've read in the file so that I may recover in the event of a failure.
I wrote the following:
string record = myTextReader.ReadLine();
bytesRead += record.Length;
ParseRecord(record);
However this doesn't work since ReadLine() strips any CR/LF characters in the line. Furthermore, a line may be terminated by either CR, LF, or CRLF characters, which means I can't just add 1 to bytesRead.
Is there an easy way to get the actual line length, or do I write my own ReadLine() method in terms of the granular Read() operations?
