title: The fastest search algorithm into binary files?
body: <p>I'm looking for the fastest and the best algorithm to search some values into a very huge binary file (kind of 2 GB AFP file), wich means that loading the whole data in memory must be inconceivable. I'm working with C# and i don't know if any other programing language (C/C++..) would be really much faster, otherwise i'll continue with C#. 
  Thanks for any ideas.</p>
