~ Operator (C# Reference)
Visual Studio 2012
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.

The ~ symbol also is used to declare destructors. For more information, see Destructors (C# Programming Guide). |
User-defined types can overload the ~ operator. For more information, see operator. Operations on integral types are generally allowed on enumeration.
