C# dynamic class inherit from dynamicobject

Dynamic object provides a base class for specifying dynamic behavior at runtime.

public class DynamicObjectInvoker:DynamicObject
    {
        public override bool TryInvokeMember(InvokeMemberBinder binder, object[] args, out object result)
        {
            Console.WriteLine(binder.Name + " method was called");
            result = null;
            return true;
        }
    }

 static void DynamicInvokeMemberDemo()
        {
            dynamic doi = new DynamicObjectInvoker();
            doi.MakeMoney();
            doi.MakeBigMoney();
        }

static void ExpandObjectDemo()
        {
            dynamic x = new ExpandoObject();
            x.FavoriteColor = ConsoleColor.Green;
            x.FavoriteNumber = 7;
            Console.WriteLine(x.FavoriteColor);
            Console.WriteLine(x.FavoriteNumber);

            var dict = (IDictionary<string, object>)x;
            Console.WriteLine(dict["FavoriteColor"]);
            Console.WriteLine(dict["FavoriteNumber"]);
            Console.WriteLine(dict.Count);
        }

C# can also interoperate with Dynamic language such as IronPython.The DLR can parse lexical and sematic statement.

 static void Main(string[] args)
        {
            int result = (int)Calculate("2*3");
            Console.WriteLine(result);
            Console.ReadLine();
        }

        static object Calculate(string expression)
        {
            ScriptEngine engine = Python.CreateEngine();
            return engine.Execute(expression);
        }
