Get a specific bit from a byte array

byte[] b = new byte[37];
     for (int n = 0; n < b.Length; ++n)
       b[n] = (byte)n;

     // get bit 5 from 37th item
     System.Collections.BitArray ba = new System.Collections.BitArray(new byte[1]{b[36]});

     Console.WriteLine("item[36][5] is {0}", ba.Get(5));
