8.13 - Reading a binay file (2 - GIF)


Create a C# program to check if a GIF image file seems to be correct.

It must see if the first four bytes are G, I, F, 8.

In case it seems correct, it must also display the GIF version (87 or 89), checking if the following byte is a 7 or a 9.


using System;
using System.IO;

public class GifFile

    public static void Main() 
        byte[] data = new byte[5];
        BinaryReader myFile;
        myFile = new BinaryReader(
            File.Open("example.gif", FileMode.Open));
