C# loading binary files

Question

Please show me the best/fast methods for:

1) Loading very small binary files into memory. For example icons;

2) Loading/reading very big binary files of size 512Mb+.

3) Your common choice when you do not want to think about size/speed but must do only thing: read all bytes into memory?

Thank you!!!

P.S. Sorry for maybe trivial question. Please do not close it;)

P.S.2. Mirror of analog question for Java;

Answer 1

1: For very small files File.ReadAllBytes will be fine.

2: For very big files and using .net 4.0 , you can make use MemoryMapped Files.

3: If Not using .net 4.0 than , reading chunks of data would be good choice
