base.cs

深入浅出C＃,学习C#比较好的用例,能够很快掌握C#.

using System;

public class Person 
{	
	protected int id;
	protected string name;
	public Person()
	{
		id=1;
		name="Jack";
	}
	public virtual void GetInfo() 
	{
		Console.WriteLine("Name: {0}", name);
		Console.WriteLine("id: {0}", id);
	}
}
class Employee: Person 
{
	private int number;
	public Employee(int number)
	{
		this.number=number;
	}
    
	public override void GetInfo() 
	{
		base.GetInfo();//使用base调用基类的方法
		Console.WriteLine("Employee number: {0}", number);
	}
}

class TestClass 
{
	public static void Main() 
	{
		Console.WriteLine("输入雇员的编号：");
		string s=Console.ReadLine();
		int number=int.Parse(s);
		Employee E = new Employee(number);
		E.GetInfo();
	}
