Very basic difference ! When you assign a reference type to another variable the object itself is not copied, rather the reference to the object is copied. Therefore, modifying one variable will reflect the change in the other variable.
When you use the Copy() method of the DataSet object, it makes a separate copy of the DataSet completely distinct from the original copy. Modifying one will not affect the other. Research the following topics : 1. Shallow copy v/s Deep Copy. 2. Heap v/s Stack 3. Reference types v/s Value types.
