Comparing two files

Question

I am comparing to files by reading it into filestream and comparing byte by byte..now how can i skip whitespaces while comparing?I am using C#.net

Answer 1

byte b;  

// ....

if (Char.IsWhiteSpace((char) b))
{
   // skip...
}

EDIT: As Eric Lippert points out, this is only correct if the encoding of the file is plain 7-bit ASCII. In any other encoding it will skip relevant bytes. So, you should take into account the encoding of your data.
