convert from BitArray to 16-bit unsigned integer in c#

Question

BitArray bits=new BitArray(16); // size 16-bit

There is bitArray and I want to convert 16-bit from this array to unsigned integer in c# , I can not use copyto for convert, is there other method for convert from 16-bit to UInt16?

Answer 1

You can do it like this:

UInt16 res = 0;
for (int i = 0 ; i < 16 ; i++) {
    if (bits[i]) {
        res |= (UInt16)(1 << i);
    }
}

This algorithm checks the 16 least significant bits one by one, and uses the bitwise OR operation to set the corresponding bit of the result.
