C # coverage

1: in Java, there is another method C and B extends a in the parent class A. To override C in B, define a C in B to automatically overwrite it.

2: in C #, It is very troublesome. First, the method of the parent class must be virtual. When the subclass overwrites the method ,,

using System;using System.Collections.Generic;using System.Text;namespace dynamicCreateClass{    class PostTask    {        public virtual void step1(){}        public virtual void step2(){}        public virtual void step3(){}    }}

using System;using System.Collections.Generic;using System.Text;namespace dynamicCreateClass{    class Site1PostTask:PostTask    {        public override void step1() { Console.WriteLine(1); }        public override void step2() { Console.WriteLine(2); }            }}

using System;using System.Collections.Generic;using System.Text;namespace dynamicCreateClass{    class Program    {        static void Main(string[] args)        {            PostTask p = (PostTask)Activator.CreateInstance(Type.GetType("dynamicCreateClass.Site1PostTask"));            p.step1();            p.step2();            p.step3();            Console.Read();        }    }}
