~ Operator (C# Reference)
The ~ operator performs a bitwise complement operation on its operand, which has the effect of reversing each bit. Bitwise complement operators are predefined for int, uint, long, and ulong.
Note
The ~ symbol also is used to declare destructors. For more information, see Destructors (C# Programming Guide).
Remarks
User-defined types can overload the ~ operator. For more information, see operator. Operations on integral types are generally allowed on enumeration.
Example
class BWC
{
static void Main()
{
int[] values = { 0, 0x111, 0xfffff, 0x8888, 0x22000022 };
foreach (int v in values)
{
Console.WriteLine("~0x{0:x8} = 0x{1:x8}", v, ~v);
}
}
}
/*
Output:
~0x00000000 = 0xffffffff
~0x00000111 = 0xfffffeee
~0x000fffff = 0xfff00000
~0x00008888 = 0xffff7777
~0x22000022 = 0xddffffdd
