请问 动态 创建list,该怎么 写

Question

外面再加一层
List<List<string>>
List<string>[]
Dictionary<string, List<string>>

Answer 1

List<List<string>> provincList
或者用字典类型，都可以的

Answer 2

Dictionary<string, List<string>>;
+1key随便起,够动态了吧

Answer 3

还是用字典集合吧，这个好用/// <summary>
        /// 省份集合
        /// </summary>
        private static Dictionary<string, List<string>> provinces = new Dictionary<string, List<string>>();        static void Main(string[] args)
        {
            //设置
            SetProvince("liaoning");            //操作
            if (provinces.ContainsKey("liaoning"))
            {
                provinces["liaoning"].Add("aaa");
            }            Console.ReadLine(); 
        }        /// <summary>
        /// 设置省份
        /// </summary>
        /// <param name="provinceName"></param>
        private static void SetProvince(string provinceName)
        {
            if (!provinces.ContainsKey(provinceName))
            {
                List<string> list = new List<string>();
                provinces[provinceName] = list;
            }
        }
