~ Operator

The ~ operator performs a bitwise complement operation on its operand. Bitwise complement operators are predefined for int, uint, long, and ulong.

~ expr

Where:

expr
An expression.

Remarks

User-defined types can overload the ~ operator (see operator).

Example

// cs_operator_bitwise_compl.cs
using System;
class Test 
{
   public static void Main() 
   {
      Console.WriteLine("!0x{0:x8} = 0x{1:x8}", 8, ~8);
      Console.WriteLine("!0x{0:x8} = 0x{1:x8}", -8, ~-8);
   }
}

Output

!0x00000008 = 0xfffffff7
!0xfffffff8 = 0x00000007
