Description

throw

Throws an exception.

The stack transitional behavior, in sequential order, is:

  1. An object reference (to an exception) is pushed onto the stack.

  2. The object reference is popped from the stack and the exception thrown.

The throw instruction throws the exception object (type O) currently on the stack.

NullReferenceException is thrown if the object reference is a null reference.

The following Emit method overload can use the throw opcode:

  • ILGenerator.Emit(OpCode)
