how to see the table of virtual function

I have two class.One class inherits from another. Also I use polymorphism with virtual function. Can I see the table of virtual function? I want to understand the mechanism of virtual functions.

public class A
{
 public virtual void foo()
 {
 }
}

public class B:A
{
  public override void foo()
  {
  }
}
...
A a=new B();
a.SomeMethod();//show table of virtual function

it's not possible to actually see the virtual table since the CLR polymorphism mechanism isn't based on a pointer allocated for each instance that points to a virtual table like you probably familiar with from C++ language.

.NET keeps a pointer to a type object for each instance, which respectively points to a method table that manages the actual implementation to be called.

Look here for more details.
