关于static和继承的问题

[guozhong111]

比如说有两个类 client 和 member。而member是继承自类client的。其中类client中有成员static protected float money;但是成员money必须是静态的，怎么才能让member中也继承一个静态的成员money;但是它和类client中的成员是不一样的呢？

静态是密封所有的对象只有一个拷贝

我写了一个,经过测试,发现并没有继承client的值, 代码如下,你参考一下,希望对你有帮助:

using System; 
using System.Collections.Generic;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using tianSystem.Common;

public partial class _Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        client client = new client();
        client._money = 110f;//设置值


        member memberZero = new member();
        Response.Write(memberZero._money + "<br/>");//测试发现并没有继承client类中的_money值, 输出为0

        member memberFirst = new member();
        memberFirst._money = 119f;//设置你想要的值
        Response.Write(memberFirst._money + "<br/>");


        member memberSecond = new member();
        memberSecond._money = 110f;
        Response.Write(memberSecond._money + "<br/>");


        //测试现有的值
        member memberThird = new member();
        Response.Write(memberThird._money + "<br/>");
    }
}


public class client
{
    static protected float money;

    public float _money
    {
        get { return money; }
        set { money = value; }
    }
}

public class member:client
{
    static protected float money;

    public float _money
    {
        get { return money; }
        set { money = value; }
    }
}

做的这个测试表明, 可以直接在member类中设置你想要的值
