The following table lists the instruction's hexadecimal and Microsoft intermediate language (MSIL) assembly format, along with a brief reference summary:
||Extract the data from
The stack transitional behavior, in sequential order, is:
An object reference
objis pushed onto the stack.
The object reference is popped from the stack and unboxed to the type specified in the instruction.
The resulting object reference or value type is pushed onto the stack.
When applied to the boxed form of a value type, the
unbox.any instruction extracts the value contained within
obj (of type
O), and is therefore equivalent to
unbox followed by
When applied to a reference type, the
unbox.any instruction has the same effect as
If the operand
typeTok is a generic type parameter, then the runtime behavior is determined by the type that is specified for that generic type parameter.
InvalidCastException is thrown if
obj is not a boxed type.
NullReferenceException is thrown if
obj is a null reference.
