Static 属性(变量)测试

May 18

原来一直以为是这么回事,却一直心中不踏实,于是试试.......嗨!! 还真是这么回事!

--------------------------------------------------

    class A
    {
        public static int a = 0;
    }

-------------------------------------------------

    class B
    {
        public void giveA1()
        {
         A.a = 1;
        }

}

---------------------------------------------------

    class C
    {
        public void addA1()
        { A.a = A.a + 1; }
    }

----------------------------------------------------

    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine(A.a.ToString());

B a = new B();

            a.giveA1();
            Console.WriteLine(A.a.ToString());

C c=new C();

c.addA1();
Console.WriteLine(A.a.ToString());

            c.addA1();
            Console.WriteLine(A.a.ToString());
        }

}
