I have a single object which can be derived from 3 separate classes.  This derived object is then passed as a parameter into another class method.  How do I determine which parent class owned my parameter?  

Please refer to the code below:

DriverFord myFord = new DriverFord();
DriverChevy myChevy = new DriverChevy();
DriverHonda myHonda = new DriverHonda();
CarWheel myWheel = new CarWheel();

myWheel = myFord.GetWheel;   //I created a Ford wheel object

SomeClass.SomeMethod(myWheel);  //How do I determine whether that wheel came from a Ford, Chevy, or Honda object?

Hi
You cannot fint that from the "myWheel" variable alone. Not unless you put something in that class which says something about the parent.
You need to get the type (.GetType() method) from the owning class (DriverFord, DriverChevy or DriverHonda).

Got it!  By using the Type.Name I was able to nail down who the parent is.  Thanks!
