Directionary字典键值对查找

using System; using System.Collections.Generic;

class test {     static void Main()     {         Dictionary<string, int> dic = new Dictionary<string, int>();         dic.Add("zhangsan", 1101);         dic.Add("lisi", 1102);         dic.Add("wangwu", 1103);         dic.Add("zhaoliu", 1104);

        foreach (string str1 in dic.Keys)         {             if (dic[str1].Equals(1103))             {                 Console.WriteLine("恭喜你！，找到了，1103对应的姓名是{0}", str1);             }         }

        foreach (string str in dic.Keys)         {              Console.WriteLine("对应的姓名是{0}:{1}",str, dic[str]);         }

    }

   1、以键找值直接Value=dic[str]

2、以值找键则可以foreach(string str in dic.Keys)

                              {  

                   if(dic[str].Equal(Value);)                        {     Console.WriteLine(str);   }

                              }
