元组（Tuple）

1.第一个例子

        private Tuple<int, int> Divide(int dividend, int divisor)
        {
            int result = dividend / divisor;
            int reminder = dividend % divisor;
            return Tuple.Create<int, int>(result, reminder);           //返回两个相同类型元素的元组
        }

       --------测试-------------

        private void button1_Click(object sender, EventArgs e)
        {
            Tuple<int, int> result = Divide(13, 2);
            Console.WriteLine("result of divison:{0}," +
                "reminder:{1}", result.Item1, result.Item2);                //用属性item1,item2访问元组的项
        }

       -------结果-------------

       result of divison:6,reminder:1

2.第二个例子

        private Tuple<int, string> MyTest2(int dividend, string Name)
        {
            int result = dividend / 2;
            string name = "Hello," + Name;
            return Tuple.Create<int, string>(result, name);      //返回两个不同类型元素的元组
        }

        --------测试-------------

        private void button2_Click(object sender, EventArgs e)
        {
            Tuple<int, string> result = MyTest2(13, "limin");
            Console.WriteLine("result of divison:{0}," +
                "Name:{1}", result.Item1, result.Item2);                //用属性item1,item2访问元组的项
        }
