Pete,
I'm not sure whether it's the best way to go , and I have not tested it either, but
(1) initialize a BitArray
(2) loop throught the string and assign the elements of the bitArray depending on 0 or 1
(3) initialize a Byte array
(4) I see that the BitARray has a CopyTo method wich accepts a Byte array
http://msdn.microsoft.com/en-us/library/system.collections.bitarray.copyto.aspxAlternatively, you can directly create a byte array and loop through the string
if( string[stringindex] == '1' ) {
the byte index = stringIndex / 8
the bit to set = 7 - (stringIndex %8),
byteArray[ stringIndex / 8] |= ( 1 << ( 7 - (stringIndex %8)))
or maybe due to widening
byteArray[ stringIndex / 8] = (byte)( byteArray[ stringIndex / 8] | byteArray[ stringIndex / 8] | ( 1 << ( 7 - (stringIndex %8))))
}
