C# Dictionary 的幾種遍歷方法

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);

            }

            //通過鍵的集合取

            foreach (string key in list.Keys)

            {

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

            }

            //直接取值

            foreach (int val in list.Values)

            {

                Console.WriteLine(val);

            } 

            //非要採用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]]);

            }
