Hex Editing in .NET

Question

I want to edit a hex location (for eg.0x90F10-0x90F15) in a DLL file.

Is there any library or APIs by which I can do it in .NET?

Answer 1

1. Call File.OpenWrite to get a FileStream for your file

2. Set Stream.Position to jump to the location you want to edit

3. Call Stream.Write to overwrite bytes in the file.

Answer 2

Since you don't provide much detail or source only a general pointer:

Try System.IO.File - you can read and write any byte/byte array...
