# VB.Net - Bit Shift Operators

Advertisements

Assume that the variable A holds 60 and variable B holds 13, then:

Operator | Description | Example |
---|---|---|

And | Bitwise AND Operator copies a bit to the result if it exists in both operands. | (A AND B) will give 12, which is 0000 1100 |

Or | Binary OR Operator copies a bit if it exists in either operand. | (A Or B) will give 61, which is 0011 1101 |

Xor | Binary XOR Operator copies the bit if it is set in one operand but not both. | (A Xor B) will give 49, which is 0011 0001 |

Not | Binary Ones Complement Operator is unary and has the effect of 'flipping' bits. | (Not A ) will give -61, which is 1100 0011 in 2's complement form due to a signed binary number. |

<< | Binary Left Shift Operator. The left operand's value is moved left by the number of bits specified by the right operand. | A << 2 will give 240, which is 1111 0000 |

>> | Binary Right Shift Operator. The left operand's value is moved right by the number of bits specified by the right operand. | A >> 2 will give 15, which is 0000 1111 |

Try the following example to understand all the bitwise operators available in VB.Net:

Module BitwiseOp Sub Main() Dim a As Integer = 60 ' 60 = 0011 1100 Dim b As Integer = 13 ' 13 = 0000 1101 Dim c As Integer = 0 c = a And b ' 12 = 0000 1100 Console.WriteLine("Line 1 - Value of c is {0}", c) c = a Or b ' 61 = 0011 1101 Console.WriteLine("Line 2 - Value of c is {0}", c) c = a Xor b ' 49 = 0011 0001 Console.WriteLine("Line 3 - Value of c is {0}", c) c = Not a ' -61 = 1100 0011 Console.WriteLine("Line 4 - Value of c is {0}", c) c = a << 2 ' 240 = 1111 0000 Console.WriteLine("Line 5 - Value of c is {0}", c) c = a >> 2 ' 15 = 0000 1111 Console.WriteLine("Line 6 - Value of c is {0}", c) Console.ReadLine() End Sub End Module

When the above code is compiled and executed, it produces the following result:

Line 1 - Value of c is 12 Line 2 - Value of c is 61 Line 3 - Value of c is 49 Line 4 - Value of c is -61 Line 5 - Value of c is 240 Line 6 - Value of c is 15
