c#基础之Dictionary

    //创建字典
            Dictionary<int, string> dic = new Dictionary<int, string>();
            dic.Add(1, "1");

            dic.Add(5, "5");

            dic.Add(3, "3");

            dic.Add(2, "2");

            dic.Add(4, "4");
            //给dic进行排序
            var result = from a in dic orderby a.Key select a;

            //遍历元素
            foreach(KeyValuePair<int,string>pair in result)
            {

                Console.WriteLine("key:‘{0}‘,value:‘{1}‘",pair.Key,pair.Value);
            }

            //只是遍历键
            Dictionary<int, string>.KeyCollection keyCol = dic.Keys;
            foreach (int key in keyCol)
            {
                Console.WriteLine("Key = {0}", key);
            }
            //只遍历值
            Dictionary<int, string>.ValueCollection valueCol = dic.Values;
