Can I define my own exceptions?

102.

Yes, as long as you follow the rule that exceptions derive from System.Exception. More
specifically, MS recommend that user-defined exceptions inherit from
System.ApplicationException (which is derived from System.Exception).

Only instances of the System.Exception classes, or classes derived from System.Exception.
This is in sharp contrast with C++ where instances of almost any type can be thrown.

None

ALL of the above
