.net 中Dictionary的遍历

            Dictionary < int ,  int >  dict  =   new  Dictionary < int ,  int > ();
            dict.Add( 200 ,  1 );
            dict.Add( 100 ,  2 );
            dict.Add( 50 ,  3 );
            dict.Add( 20 ,  4 );
             foreach ( KeyValuePair < int , int >  entry  in  dict)
            {
                Console.WriteLine(
                     string .Format( " key:{0}/nvalues:{1}/n " ,
                                  entry.Key,
                                  entry.Value
                                 )
                );
            }
示例一出....就全明白了...
