  • Dictionary的几种遍历方法

    Dictionary<string, int> list = new Dictionary<string, int>();

     

                list.Add("d", 1);

     

                //3.0以上版本

                foreach (var item in list)

                {

                    Console.WriteLine(item.Key + item.Value);

                }

                //KeyValuePair<T,K>

                foreach (KeyValuePair<string, int> kv in list)

                {

                    Console.WriteLine(kv.Key + kv.Value);

                }

                //过键的集合取

                foreach (string key in list.Keys)

                {

                    Console.WriteLine(key + list[key]);

                }

                //直接取值

                foreach (int val in list.Values)

                {

                    Console.WriteLine(val);

                } 

                //非要采用for的方法也可

                List<string> test = new List<string>(list.Keys);

     

                for (int i = 0; i < list.Count; i++)

                {

                    Console.WriteLine(test[i] + list[test[i]]);

                }
