C＃抽象类，使用匿名而不是声明具体类？

Question

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?

Answer 1

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
           });
