How to convert a string of bits to byte array

Question

I have a string representing bits, such as:

\"0000101000010000\"

I want to convert it to get an array of bytes such as:

{0x         


        

Answer 1

Use the builtin Convert.ToByte() and read in chunks of 8 chars without reinventing the thing..

Unless this is something that should teach you about bitwise operations.

Stealing from Adam (and overusing LINQ, probably. This might be too concise and a normal loop might be better, depending on your own (and your coworker's!) preferences):

public static byte[] GetBytes(string bitString) {
    return Enumerable.Range(0, bitString.Length/8).
        Select(pos => Convert.ToByte(
            bitString.Substring(pos*8, 8),
            2)
        ).ToArray();
}
