An | operation operates on a Boolean constant.
C# has a bitwise and a logical-AND operation on Booleans, that is, & and &&. Similarly, C# has a bitwise and a logical-OR operation | and ||. The difference is that the logical operations have a short circuit semantics, that is, if the evaluation of the left-hand side is enough to determine the outcome of the operation, then the right-hand side is not evaluated; the bitwise operations, instead, evaluate both sides, always, which might be incorrect is most cases, or at least inefficient.
