    Hi,
    I have some questions regarding bitvector32 and bitarray.

    1.what is the difference between bitvector32 and bitarray?

    2.what is the difference between bitvector32(1) and bitvector32(-1)?

    3.why the performance of bitvector32 is greater than the bitarray?


    Regards
    Vinit

    According to the MSDN:
    'BitVector32 is more efficient than BitArray for Boolean values and small
    integers that are used internally. A BitArray can grow indefinitely as
    needed, but it has the memory and performance overhead that a class instance
    requires. In contrast, a BitVector32 uses only 32 bits.'

    BitVector32 is a struct and consumes only 4 bytes. BitArray is a class that has overheads associated with it and is therefore less efficient - BitArray will need at least 8 bytes before you've even added any objects to it as it lives on the heap.
