I need to read binary PGM image files. Its format:

P5
# comments
nrows ncolumns
max-value
binary values start at this line. (totally nrows*ncolumns bytes/unsigned char)

I know how to do it in C or C++ using FILE handler by reading several lines first and read the binary block. But don’t know how to do it in .Net.
