Class TestBase {static void Main () {Employye employee = new Employye (); employee. getInfo (); Console. read () ;}} public class Person {public string Name = "jing"; public int Age = 20; public virtual void GetInfo () {Console. writeLine ("Name: {0}, Age: {1}", Name, Age) ;}} public class Employye: Person {public string Id = "123456 "; public override void GetInfo () {base. getInfo (); Console. writeLine ("employee Id: {0}", Id );}}
