C# Abstract class, using anonymous instead of declaring concrete class?

I have an abstract class and I would like to use it quickly by NOT create a concrete class that inherit the abstract class. Well, to define the abstract method anonymously.

Something like that:

           Command c = new Command(myObject){
               public override void Do()
               {
               }                   
            };

Is it possible in C# .net 2.0?

• You could create a type that wraps an action providing an implementation as such:

  class ActionCommand
  {
      private readonly Action _action;
  
      public ActionCommand(Action action)
      {
          _action = action;
      }
  
      public override void Do()
      {
          _action();
      }                   
  };
  

  This then can be used as so:

  Command c = new Command((Action)delegate()
             {
                // insert code here
             });
