computerpublic wrote:
string temPath = Path.GetTempFileName();

From the MSDN documentation:

Creates a uniquely named, zero-byte temporary file on disk and returns the full path of that file.

You have created an empty file; when you try to read it, you won't get any bytes returned, because it's empty.

computerpublic wrote:
Console.WriteLine("{0}={1}",arry[count],buffer[count]);//THE VISUAL PRESENTATION DOES NOT WORK

As you've written it, the code would print out "NUMBER=NUMBER" for each byte in the input file. Since there are no bytes in the input file, it won't have anything to display.


computerpublic wrote:
string filePath2 = Path.Combine("C:\\check", Path.GetFileName(filePath)); //THE OUTPUT FILE DOES NOT WORK
output.Write(buffer, 0, bytesRead);

Apart from the fact that the input file is empty, your code suggests that you're trying to write to a file in the directory C:\check, but you're actually writing to another temporary file, which will be in the %TEMP% folder.


computerpublic wrote:
turn each byte into a number and SHOW IT, turn the number back to a byte and SHOW IT

A byte is a number. It's a number between 0 and 255. There's no need to turn it into a number.

Saying "I need to turn this byte into a number" is like saying "I need to turn this fluid into a liquid". There's no conversion needed.

What I suspect you want to do is display the byte in different number bases - for example, in binary (base 2) and decimal (base 10). That's just about formatting the number, not converting it to a different type.



Based on your description, the following code should do what you're after:

using System;
using System.IO;

namespace Applica
{
    static class Program
    {
        DirectoryInfo da = new DirectoryInfo("C:\\Folder1");
        if (!da.Exists)
        {
            Console.WriteLine("The folder '{0}' does not exist.", da.FullName);
            return;
        }
        
        FileInfo[] Arr = da.GetFiles();
        if (Arr.Length == 0)
        {
            Console.WriteLine("There are no files in the folder '{0}'.", da.FullName);
            return;
        }
        
        FileInfo ap = Arr[Arr.Length - 1];
        long Totbyte = ap.Length;
        string filePath = ap.FullName;
        Console.WriteLine("Total Bytes = {0} bytes", Totbyte);
        
        const int BufferSize = 1024;
        byte[] buffer = new byte[BufferSize];
        
        string destinationPath = Path.Combine("C:\\check", Path.GetFileName(filePath));
        
        using (Stream input = File.OpenRead(filePath))
        using (Stream output = File.OpenWrite(destinationPath))
        {
            int bytesRead;
            while ((bytesRead = input.Read(buffer, 0, BufferSize)) > 0)
            {
                for (int count = 0; count < bytesRead; count++)
                {
                    byte theByte = buffer[count];
                    string theByteInBinary = Convert.ToString(theByte, 2).PadLeft(8, '0');
                    Console.WriteLine("{0} = {1}", theByteInBinary, theByte);
                }
                
                output.Write(buffer, 0, bytesRead);
            }
        }
    }
}
