Answer 1

It sounds like you want to use a delegate here.

Basically, you can add, in class "B":

class B
{
    public Action TheMethod { get; set; }
}

class A
{
    public static void Foo() { Console.WriteLine("Foo"); }
    public static void Bar() { Console.WriteLine("Bar"); }
}

You could then set:

B b = new B();

b.TheMethod = A.Foo; // Assign the delegate
b.TheMethod(); // Invoke the delegate...

b.TheMethod = A.Bar;
b.TheMethod(); // Invoke the delegate...

This would print out "Foo" then "Bar".
