Bool To bit/byte

If you're wanting to pack 8 bools into a single byte using the usual convention that true is 1 and false is 0, then the PackBools method in this program should do it.

For the purposes of this method, b0 is assumed to represent the least significant and b7 the most significant bit of the resulting byte:

using System;

class Test

{

static void Main()

{

byte b = PackBools(true, true, true, true, true, true, true, false);

Console.WriteLine(b.ToString("X2")); // 7F

Console.ReadKey();

}

static byte PackBools (bool b0, bool b1, bool b2, bool b3, bool b4, bool b5, bool b6, bool b7)

{

int temp = 0;

if (b0) temp += 1;

if (b1) temp += 2;

if (b2) temp += 4;

if (b3) temp += 8;

if (b4) temp += 16;

if (b5) temp += 32;

if (b6) temp += 64;

if (b7) temp += 128;

return (byte)temp;

}
