赋值

  List<Tuple<string, int>> cc = new List<Tuple<string, int>>()
            {
                new Tuple<string, int>("满减5", 1),
                new Tuple<string, int>("满减2", 2),
                new Tuple<string, int>("满减5", 3),
                new Tuple<string, int>("满减1", 4)
            };

取值

1  foreach (var item in cc)
2             {
3                  string ite = item.Item1;
4                 int ctNum = item.Item2;
5             }

说明：可以当一个简单的类来用
