Question

How can I convert BitArray to a single int?

Answer 1

private int getIntFromBitArray(BitArray bitArray)
{

    if (bitArray.Length > 32)
        throw new ArgumentException("Argument length shall be at most 32 bits.");

    int[] array = new int[1];
    bitArray.CopyTo(array, 0);
    return array[0];

}
