Casting one object to another

Question

I have to Classes. lets say Invoice and TempInvoice. Both have same properties(all are same). let say i created a object using Invoice Class. Can i cast that object to another object that i created using tempInvoice ??

ex:

Invoice invoiceobj= getInvoice(int? id) //a method return a invoice object

TempInvoice tempInvoiceObject = invoiceobj// (Need to do it and fill tempInvoice by Invoice Values.even as a new memory location o set by reference.)

Answer 1

Not unless Invoice derives from TempInvoice.
