Hello MVPs:

I am not sure when to use binaryreader in .net is best?
In fact ,I am coding a program which converts data in text files
into DB. but i have to use fixed length to read data in file(old format).
Here fixed length means the count of bytes read not the count of chars read.
because there are 2-byte chars in the data file. What about to use
binaryreader to read a text file to solve this problem.
If i use streamreader,how to accomplish it?

thanks in advance.

When you're reading a *binary* file containing primitives encoded in
the way that BinaryReader understands, IME.

StreamReader sounds like the way to go. Are there line breaks between
records, by any chance? If so, just use ReadLine to read a line at a
time, and break up the string with Substring.

It's *slightly* more tricky otherwise, because you'll need to read into
a buffer of the right size repeatedly until the buffer is full, then
process that record. Far from difficult though.
