Exercise 8.9:

Reading a binary file (1: BMP)


Objetive:

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

It must see if the first two bytes are B and M (ASCII codes 0x42 and 0x4D).


Source Code:


using System;
using System.IO;
public class BmpFile
{

    public static void Main()
    {
        byte data1, data2;

        //Open file
        BinaryReader myFile;
        myFile = new BinaryReader(File.Open("1.bmp", FileMode.Open));

        // Read data
        data1 = myFile.ReadByte();
        data2 = myFile.ReadByte();

        //Close file
        myFile.Close();

        //Check Data
        if ((data1 == 0x42) && (data2 == 0x4D))  // B M
            Console.WriteLine("It seems to be a BMP file");
        else
            Console.WriteLine("It DOES NOT seem to be a BMP file");
    }
}
