dictionary 应用（绑定dgv）

Posted 2020-08-09 肥皂泡泡oO

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);
            } 

实际应用

  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
        }
