# C# - Bitwise Operators

Advertisements

The Bitwise operators supported by C# are listed in the following table. Assume variable A holds 60 and variable B holds 13, then −

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

& | Binary AND Operator copies a bit to the result if it exists in both operands. | (A & B) = 12, which is 0000 1100 |

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

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

~ | Binary Ones Complement Operator is unary and has the effect of 'flipping' bits. | (~A ) = 61, which is 1100 0011 in 2's complement due to a signed binary number. |

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

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

## Example

The following example demonstrates all the bitwise operators available in C# −

Live Demousing System; namespace OperatorsAppl { class Program { static void Main(string[] args) { int a = 60; /* 60 = 0011 1100 */ int b = 13; /* 13 = 0000 1101 */ int c = 0; c = a & b; /* 12 = 0000 1100 */ Console.WriteLine("Line 1 - Value of c is {0}", c ); c = a | b; /* 61 = 0011 1101 */ Console.WriteLine("Line 2 - Value of c is {0}", c); c = a ^ b; /* 49 = 0011 0001 */ Console.WriteLine("Line 3 - Value of c is {0}", c); c = ~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(); } } }

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
