question about binary file access

[Bit byte]

If I write data from structures to a binary file in C#, can I read back
the file using "unmanaged" C++ ?

Bit byte,

You could, but you would have to use unmanaged functions through the
P/Invoke layer (specifically, the ReadFile method) and unsafe code (so you
can get a direct pointer to the structure to populate).

Hope this helps.

I disagree with this. You should be able to write them to a binary file
without issue and read them from your unmanaged C++ ...

Are you thinking the other direction Nicholas? Even then you should be able
to read them without too much of a problem.

Hi Bit byte,

Well of course! Are you having a problem with it? If you're just writing
to a file, then you can open that file with anything that can open files,
and read it.

If your structs are managed, not unmanaged, you can serialize them to a byte
array with the BinaryFormatter class and write them to a file. Just as well,
you can read this file back into a byte array and perform the reverse
operation.

Greg,

Yes, I was thinking of the other way. It would actually be done in a
surprizingly similar way in unmanaged C++ (same API call, etc, etc);
