Thanks for the release, but i already know how to do that (though more functions than i know)
If you knew how write tell me xD

#Edit : ExtractFile, It writes the data and never close the writer ^^

Awesome, let's snap our jaws on another small bit of C# code! :)

Currently examining it. :3

Nice to see that someone did something with my code. :)
You should try importing files as well. That should be a bit more of a challenge. ;)

Going to test / review the results.

Result as your code: [Only registered and activated users can see links. Click Here To Register...]
And , where's the extract point? It only reads right?
I may work a lil bit on it but as a form * I hate consoles * and , I will post my final modified version.

@phoenix1337:
The example is just an example. You can also work with a GUI instead of a console.

For extracting a file:
<Instance of Reader>.ExtractFile(File file, string OutputPath)

UPDATE:
- Fixed "ExtractFile()" - Writer now closes... (thx for the report)

Why do you use it in dll format? + Every command in your console , it closes the console automatically .
03/11/2013 14:38 intercsaki#8
Well, dll can be easily imported and used in applications. But one can use the source included, just bother to copy everything. :D Pros and cons at both side.

.Net DLLs source code are easy to recover. Just use ILSpy or something like that. And about copying everything... Once you have a great solution for a problem, you are noob if u dont use that... Also you shouldnt use .Net or some classes in C#... You can write them from yourself ;)

A noob , as you've said , at least he's helping people . Unless your worthless comment which creating a false point 100%. If he's a noob , we should teach him how to manage these shits , To become a pro.

lets make pk2 writer

simple writer fonction

public void WriteFile(string Source, string InputPath)
{
//gösterilen dosyayı oku
System.IO.FileStream str = new System.IO.FileStream(Source, System.IO.FileMode.Open);
System.IO.BinaryReader readbnr = new System.IO.BinaryReader(str);
Byte[] data = readbnr.ReadBytes((int)str.Length);
str.Close();

//yaz
System.IO.BinaryWriter wrt = new System.IO.BinaryWriter(m_FileStream);
File file = m_Files.Find(item => item.Name.ToLower() == Source.ToLower());
wrt.BaseStream.Position = file.Position;
wrt.Write(data);
wrt.Close();
}

How to use
first extract config.txt in mini.pk2
change config.txt
pk2Reader.ExtractFile("config.ini", "config.ini");
...

Problems..
Its works but you cant write extra byte from old data lenght

In my opinion, the main pont was this:
