Question

Is there any predefined function available to convert a byte into BitArray?

One way would be to inspect every bit of the byte value and then perform bitwise operation. I was wondering if there is any way which is more straightforward than this.

Answer 1

Yes, using the appropriate BitArray() constructor as described here:

var bits = new BitArray(arrayOfBytes);

You can call it with new BitArray(new byte[] { yourBite }) to create an array of one byte.
