Simple OOP Casting Question

[atmosphere1212]

Is it possible to cast down to an object that doesnt exist?

 

ie

 

temp = (SomeClass)objInstance

 

where objInstance is an instance of a parent object, and SomeClass is the object I want. Note that objInstance is not an instance of SomeClass, just its parent

If temp is declared as the parent object then yes, you can make it equal to a sub-class. In fact you can always implicitly cast to a base class i.e. you don't even need the (...) bit.
