bitwise xor is giving the wrong result

[Tony Johansson]

Hi!

How on earth can the result on xorbits be true when you are doing an xor
between two
bits where each bit is true it should be false ?

public void Main(string[] args)
{
BitArray bits = new BitArray(1);
bits[0] = true;

BitArray morebits = new BitArray(1);
bits[0] = true;

BitArray xorbits = bits.Xor(morebits);

foreach (bool bit in xorbits)
Console.WriteLine(bit);
}

//Tony

Because you mistakenly initialized bits[0] to true twice, leaving
morebits[0] initialized to false, resulting in the evaluation
false xor true
