What does '^' do in c# (Enums)?

Question

I was reading some 3rd party code and I found this:

x.Flags = x.Flags ^ Flags.Hidden;

What does it do?

I\'ve used \'&\' and \'|

Answer 1

^ is the bitwise XOR operator in C#.

EDIT: a ^ b returns true if a is true and b is false or if a is false and b is true, but not both.
