C # bitwise operator Collation _c# Tutorial

The bit logic operators supported by C # are shown in table 2.9.

1, bit logical non-operation

Bit logical non-operation is a single purpose, only one Operation object. Bitwise logical operations do not operate on the value of an Operation object by bitwise, that is, if one is equal to 0, it is converted to 1, and if one is equal to 1, it is converted to 0.

For example, the binary 10010001 bitwise logic is not operational, the result is 01101110, in decimal notation is:

The ~145 equals 110, and the binary 01010101 is bitwise-logical, and the result equals 10101010. In decimal notation is ~85 equals 176.

2 , bit logic and Operation

The bitwise logic and operation of the two operations object bitwise AND operation. With the operation of the rule: 1 and 1 equals 1, 1 and 0 equals 0.

For example: 10010001 (binary) &11110000 equals 10010000 (binary).

3, bit logic or operations

Bitwise logic or an operation to bitwise or operate on two operations objects. Or the rule of operation is: 1 or 1, etc. 1, 1 or 0 equals 1,

0 or 0 equals 0. Like 10010001 (binary) | 11110000 (binary) equals 11110001 (binary).

4 , bitwise logical XOR, or Operation

A bitwise logical XOR OR operation converts two operations objects to or from a bitwise. The rule of XOR or operation is: 1 xor or 1 equals 0,

1 xor or 0 equals 1, 0 is different or 0 is equal to 0. That is: the same 0, the difference is 1.

For example: 10010001 (binary) ^11110000 (binary) equals 01100001 (binary).

5 , bit left shift operation

The left shift operation shifts the entire number of digits to the left, and the vacated portion of the left 0. For example: A 8-bit byte variable

Byte a=0x65 (that is, binary 01100101) moves it left 3 bits: The result of A<<3 is 0x27 (that is, binary 00101000).

6 , bitwise right SHIFT operation

The bitwise right SHIFT operation shifts the entire number of digits to the right, and the vacated portion of the right is filled with 0. For example: A 8-bit byte variable

Byte a=0x65 (both (binary 01100101)) shifts it to the right 3 bits: The result of A>>3 is 0x0c (binary 00001100).

The type of the result of the operation is the type of the Operation object, if the type of the two operands is the same for the bitwise, OR, XOR, or operation. For example, two int variables A and B are done with operations, the type of the result of the operation is int type. If two operations

Object, C # will convert the inconsistent type to a consistent type and then perform the operation.

The rules for type conversions coincide with the conversion of integral types in arithmetic operations.

An expression that is connected by a bitwise operator to an integral type is a bitwise operation expression.
