not

Computes the bitwise complement of a value.

The stack transitional behavior, in sequential order, is:

  1. value is pushed onto the stack.

  2. value is popped from the stack and its bitwise complement computed.

  3. The result is pushed onto the stack.

The not instruction computes the bitwise complement of an integer value and pushes the result onto the stack. The return type is the same as the operand type.

The following Emit method overload can use the not opcode:

  • ILGenerator.Emit(OpCode)
