2023-04-20 C#: bit Reverse in a Byte

I need a bit reverse in a byte function.
[b7][b6][b5][b4][b3][b2][b1][b0]
convert into
[b0][b1][b2][b3][b4][b5][b6][b7]
Here is my solution.

Solution

private byte ReverseBits(byte inData)
{
	inData = (byte)(((inData & 0x0F) << 4) | ((inData & 0xF0) >> 4));
	inData = (byte)(((inData & 0x33) << 2) | ((inData & 0xCC) >> 2));
	inData = (byte)(((inData & 0x55) << 1) | ((inData & 0xAA) >> 1));

	return inData;
}
