Hi, I would like to know how I can dump the section of a NATIVE executable using c# ? 

PS : the section I would like to dump is an added section (so not .text, .reloc, .rsrc)

Thanks you

Walk the PE header like normal, enumerate the sections and dump the target section you want. There is nothing special about it being a native image or that you are coding in C#.

Here is code I wrote for my Steamless project to read the PE headers of files:

32bit: https://github.com/atom0s/Steamless/tree/master/Steamless.API/PE32

64bit: https://github.com/atom0s/Steamless/tree/master/Steamless.API/PE64

You might wanna check https://corkamiwiki.github.io/PE probably steam doesn't output these exotic files, but it's still worth checking out alignment on PointerToRawData and SizeOfRawData being ignored if VirtualSize is smaller.

That was for making an unpacker for BoxedAppPacker (.net) so all is working fine
