C# Equivalent of bitset Flip method

Question

1.50/5 (2 votes)

See more:

I have a BitArray which I need to flip. In C++ you can just use the following syntax:

C++

bitset<5> MyBitset (mystring);
MyBitset.flip();

How can I achieve the same result in C#? Also, I now need to take this bitset (well, BitArray in C#) and convert it to a double. In C++ I can just us the .to_ulong() method, however, C# does not give me that option :/

Any help will be awesome!

Thanks in advance.

Solution 1

Use the Not() method of the BitArray class.

Edit: Here is a link for info about BitArray
http://msdn.microsoft.com/en-us/library/system.collections.bitarray.aspx[^]
Edit 2: You may want to check out the BitConverter class maybe it can help to convert BitArray to double.

I need to reverse the order of the bits, this wont work! I have made a solution for this though!

BitConverter doesnt have an overload that takes a bool[], which is what a BitArray is.

Well as far as I know the flip() function of bitset does not do this either!
You need to be more clear when posting question.

as I said, that is no longer the issue! I know need to convert the bit array to a double

I am sorry I just don't know right now how to do this. Maybe someone else will come along that knows how to help you. Also calling .to_ulong() on a bitset returns an unsigned long not a double?!?
