Remarks

Whether the option is critical.

This property reflects whether the option is critical or elective. Receivers that do not recognize a critical option must return a 4.02 "Bad Option" response code back to the sender. Unrecognized elective options can be safely ignored.

The RequestOptionIndex parameter specifies the index of the item in the array. The size of the array is controlled by the RequestOptionCount property.

This property is read-only and not available at design time.
