Please don't remove any messages that have been replied to. It is against the forum guidelines as it results in messy threads.

Yours said:

which is what you also replied to Covean !?!?!?

I figured originally i intend to reply to Covean, but instead went to you. To avoid further confusion I removed it (MOVED back to under Covean's thread)

@devvvy: YOU don´t understand: You were asked to provide the piece of code making troubles .... you didn´t, instead you started to moan ... ANYWAY:

byte[] an_image = File.ReadAllBytes("hello_world.exe");
File.WriteAllBytes("another_hello_world.exe", an_image);

No P/Invoke, not really difficult ...

hey thanks it works!

I must have made a mistake - I thought I tried ReadAllBytes too but apparently not.

If I'm right then he asks for a way to read all the file data plus the file system (NTFS as example) specific information.
On a hard disk there are also a file header / footer for every file.
Now this data he wants to read (and maybe) write.

1. Handle a file is the wrong approach you have to handle the file system in your case.
2. There is no class (or?) to read/write from/to the hard disk at this i/o level in C#.
3. Take a look at CreateFile. There is a possibility to read the physical disk.

He didn't "understand" you. He frickin' guessed at it using the link you posted and your replies in this thread.

I took a look at the link and guessed that you were trying to read the entire contents of the file, uninterpreted, because of the HexEdit screen shots in the link and your mentioning of using Encoding to read the file. You made no mention at all of what you were ultimately trying to do with this information.

Luc is correct. You still don't know how to ask a question in a format that is answerable, nor do you provide any of the details to questions that would fill in the missing bits of information critical to giving you the correct answer on the first try. You've demonstrated a history of this. People have to constantly guess at what you're talking about.

screw you sis go find someone else to argue with, if you don't know the sh*t, don't litter the forum pass on to another thread which you actually have something to offer

The only way someone can actually offer you anything useful is if they take a wild ass guess at what your trying to do.

and why do you think Covean gave me the answer I was looking for? There's troops of losers littering this forum these days - like i said, if you have no better to say just move on and play with yourself

This can be done in .NET / C# by using PInvoke.
But on the other hand I think that accessing the file system directly from C# should be avoided.

If you have problems to get started with this, google for "PInvoke" and try to figure out how to call Windows API from within C#.

PS: To get a better start with this forum and all those helper/cpians here, please read the pinned forum guidelines at the start and try to think about / rephrase your question. One more sentences could avoid further inquiry.

I understand pinvoke, but why ... that such things done via platform win32 api better...?

I just only know this way ... so why should be something better to the only way I know ... better than what?
Let me know if you know an other way, than maybe we could speak about things like that one way is better than the other
... but how should I be able to tell you if win32 api platform invoke is better than ... what???

It can be done WITHOUT P/Invoke

Why? For what reason is the namespace "System.IO"?

Re: thanks yes you understand me - i will post the code but you're suggesting this can't be done in dotnet? x

11-Aug-10 2:30

And what class from System.IO allows direct access to the hard disk/file system (and how)?
And as I mentioned before, I don't know if there is a way without PInvoke, this doesn't mean there
is no way!
