problem to read binary file

[Quinn]

Hi all,

I have some binary files in the following format:

text line 1
text line 2
....
text line N
end of text
single in binary 1 single in binary 2 single N EOF
what I want to do is, to read text line by line until reached "end of text",
the start read binary numbers.

I start with a binaryreader

br.readstring until regex.ismatch(br.readstring) is true, then start
readsingle.

the problem is, the binary files were generated from VB6 program, the
br.readstring length does not match the VB6 string length. so sometimes the
"end of text" cannot be found.
I also think I can use a stream read to read the text first, then use the
binaryreader to read the binary part. but I cannot find the location where
the binary started.

Please help.

Suggestion:

Read the file into a byte-array. Convert each byte in the array into a
string, one byte at a time and append to a string. If the string ends with
(EndsWith method) "end of text", then you have reached the start of the
binary data :)
