Question

I have string which is storing only 1’s and 0’s .. now i need to convert it to a byte array. I tried ..

System.Text.UTF8Encoding encoding = new System.Text.UTF8Encoding();
                        byte[] d = encoding.GetBytes(str5[1]);

but its giving me byte array of ASCIIs like 48’s and 49’s but i want 1’s and 0’s in my byte array.. can any one help

Answer 1

That is the correct result from an encoding. An encoding produces bytes, not bits. If you want bits, then use bit-wise operators to inspect each byte. i.e.

foreach(var byte in d) {
    Console.WriteLine(byte & 1);
    Console.WriteLine(byte & 2);
    Console.WriteLine(byte & 4);
    Console.WriteLine(byte & 8);
    Console.WriteLine(byte & 16);
    Console.WriteLine(byte & 32);
    Console.WriteLine(byte & 64);
    Console.WriteLine(byte & 128);
}
