Hi
How do I read binary from any file, then rewrite the binary to a new file.

This is needed, because I am trying to compress the binary, then rewrite it to a new file, with the aim to uncompress it, keeping all contents intact.

This is for a C# Express 2010 Project.

I figured out a way to get 1MB, to mabey 100k. How this could be done is through searching for duplicate code (100000010) etc, then creating an array storing the loction of the code, rather than the code itself.

Solution 1

Good luck with the compression algorithm - I suspect that it will be a lot less successful than you think...:laugh:

However, to read binary:

C#

byte[] bytes = File.ReadAllBytes(path);

To write it again:

C#

File.WriteAllBytes(path, bytes);

Solution 2

If your objective is just to copy a file, you can use the File.Copy. See: http://msdn.microsoft.com/en-us/library/system.io.file.copy.aspx[^]
