logical operators for C #

The C # language provides three kinds of logical operators:

&& Logic and

| | Logical OR

! Logical Non

Where logic and logic or both are two-element operators, require two operands. The logic is not a unary operator, only one operand. Their operands are all Boolean-type values or expressions. When operands are in different combinations, the results of the logical operators can be expressed in the "truth table" of logical operations, as shown in tables 7-6:

Table 7-6 Truth Tables

A	B	!a	A&&b	a| | B
True	True	False	True	True
True	False	False	False	True
False	True	True	False	True
False	False	True	True	False

If there are multiple logical operators in the expression at the same time, logical non precedence is highest, logical and precedence over logic or.
