Britney,
Virtual functions are the base of overloaded functions. The method on
the base class that can be overridden is virtual, indicating that any class
deriving from that class can override the function.
Interfaces are different from abstract classes because they can not have
implementations (method bodies, fields, etc, etc), where abstract classes
can.
Hope this helps.

Hi Nicholas,
I thought when class is Abstract, you can override base class
(changing the implementation)
I'm confused between OVERRIDE and OVERLOAD now.

Britney,
When a class is abstract, you can override the base class (that base
class being the abstract class).
When you overload a method, you are providing multiple methods with the
same name, but different signatures. When you override a method, you are
providing an implementation that the base class will use when it is called.
For example, this is overloading:
public void DoSomething()
{
DoSomething(0);
}
public void DoSomething(int val)
{
Console.WriteLine(val);
}
You are providing the same method with two different signatures. When
you override, you have something like this:
public class Base
{
public virtual void DoSomething()
{
Console.WriteLine("Called DoSomething from Base.");
}
}
public class Derived : Base
{
public overrides void DoSomething()
{
Console.WriteLine("Called DoSomething from Derived.");
}
}
Base b = new Derived();
b.DoSomething();
When you run the above two lines, DoSomething will print out "Called
DoSomething from Derived.".

Britney,
XML serialization will serialize an instance into XML, but it will only
serialize the public fields/properties in the objects exposed in the object
graph.
SOAP serialization is a complete serialization of the object instance's
private fields (and all the private fields of references maintained by the
object). It's a much more accurate representation of the object, but not
very human-readable.
