For bool? operands, the & (logical AND) and (logical OR)operators support the three-valued logic as follows: 1. The & operator produces true only if both its operands evaluate to true. If either x or y evaluates to false, x & y produces false (even if another operand evaluates to null). Otherwise, the result of x & y … See more The unary prefix ! operator computes logical negation of its operand. That is, it produces true, if the operand evaluates to false, and false, if the operand evaluates to true: The unary postfix ! operator is the null-forgiving operator. See more The operator computes the logical OR of its operands. The result of x y is true if either x or y evaluates to true. Otherwise, the result is false. The operator evaluates both operands even … See more The & operator computes the logical AND of its operands. The result of x & y is true if both x and y evaluate to true. Otherwise, the result is false. … See more The ^ operator computes the logical exclusive OR, also known as the logical XOR, of its operands.
