How to use the file buffer read method with vb.net 2005 ?

Question

Hi,

I'm searching for an example about streamreader with method (buffer,index,count) to be able to read faster files than byte by byte.

I get Unix files with \n line delimiter and I need to analyse the line to retrieve a string.

I wrote a program with the streamreader object but that reads byte by byte and it's not very efficient.

I have some 300 Mo jobs so I need to optimize it.

Does anybody could post a code examploe to help me or some advise to do that.

I read MSDN articles but are not very clear.

Thanks in advance
