Technically, no, dynamic programming just means solving smaller problems as part of a larger problem.

eg. dykstras algorithm for a shortest path, or a merge sort.

I think you're thinking of dynamic typing, which .NET and F# have, kinda, (via dynamic method invocation). In F# to invoke a method dynamically use the ? operator.

  x.Bar() # static call
  x?Bar() # dynamic call

in C# to do a dynamic call cast the object to Dynamic.

  ((Dynamic)x).Bar(); // dynamic call
  ((IFoo)x).Bar(); // static call

Also, you can do multiple inheritance in a static language, C++ as an example.
