C#根据输入的字符串来创建类的实例

abstract class Vehicle    {        public abstract void Drive();    }        class Car : Vehicle    {        public override void Drive()        {            Console.WriteLine("Car is driving...");        }    }    class Bus : Vehicle    {        public override void Drive()        {            Console.WriteLine("Bus is driving...");        }    }    class Program    {        static void Main(string[] args)        {            string typeName = Console.ReadLine();            Type type = Type.GetType(new Program().GetType().Namespace + "." + typeName, true, true);            Vehicle vehicle = (Vehicle)Activator.CreateInstance(type);            vehicle.Drive();            Console.ReadKey();        }    }
