Base and This

[elfin sequoia]

this is the current object the code is executing on, the context the code runs on

base is accessor for the superclass

[trim quarry]

and in which case do you use it?

[elfin sequoia]

base most often for calling implementation of virtual/abstract methods in the base class

this when you need to differentiate the local variable, from member variable, or any other case when you need to access current object, or pass it somewhere

class Foo{
  public void AcceptBar(Bar bar)  {}
}

class Bar{
  void DoStuff()
  {
  var f = new Foo();
  f.AcceptBar(this);
  }
 }
