??? o = new ???();
Console.WriteLine("ToString() -> " + o.ToString() ); //<--- Prints 'ToString() -> '
Console.WriteLine("GetType() -> " + o.GetType()); //<--- NullReferenceException
Output:
ToString() ->
Unhandled Exception: System.NullReferenceException: Object reference not set
to an instance of an object.
at System.Object.GetType()
at Program.Main(String[] args)
What is the type ???
and why does o.ToString()
return string.Empty
and o.GetType()
throws a NullReferenceException
?
Note:
GetType()
is not redefined in the???
type.
Any Nullable<T>
.
