dictionary的用法：//初始化添加所有车位进这队列            Utility.Effectlist.Add("Carlot", 0);            //每触发一次，用这个增加数量            Utility.Effectlist["Carlot"]++;            //遍历显示            foreach (var item in Utility.Effectlist)            {                Console.WriteLine("key:{0} value:{1}", item.Key, item.Value);            } 

  private void button8_Click(object sender, EventArgs e)        {            Dictionary<string, int> templist = new Dictionary<string, int>();            foreach (var item in Utility.Effectlist)            {                templist.Add(item.Key, 0);              //  Utility.Effectlist[item.Key] = 0;               // dgvCountShow.DataSource = Utility.Effectlist.ToArray();            }            Utility.Effectlist.Clear();            Utility.Effectlist = templist;            dgvCountShow.DataSource = Utility.Effectlist.ToArray();//绑定到dgv        }
