请问：这个使用Dictionary遇到的问题 ？？

Question

我在Project 用一个结构来装载一些信息             Dictionary<string, Dictionary<string, int>> dic_Total = new Dictionary<string, Dictionary<string, int>> ();            Dictionary<string, int> dic_Point = new Dictionary<string, int> ();  // 就是 dic_Total装载着dic_Point            // 在循环里面 装载满了一个 dic_Point时候将它     
              for ( int n = 0; n < 100; n++ ) {
                dic_Point.Add ( n.ToString(), n );                if ( n % 5 == 0 ) {
                    dic_Total.Add (n.ToString(), dic_Point );
                    dic_Point.Clear ();
                }            } 
            Console.Read ();   
     
     发现执行之后 dic_Total每个记录的 Value都是相等的 就是 dic_Point最后那个值 ， 96，97，98，99      
     当   for ( int n = 0; n <= 100; n++ ) 时 执行了 dic_Point.Clear (); 
     然后 dic_TotalValue的东西都清空了，是 Dictionary 记住的都是地址 ？
     假如我想要存储这样结构应该怎么办？ 求求解答..... 谢谢！

 Dictionary<string, Dictionary<string, int>> dic_Total = new Dictionary<string, Dictionary<string, int>> ();            Dictionary<string, int> dic_Point = new Dictionary<string, int> ();  // 就是 dic_Total装载着dic_Point            // 在循环里面 装载满了一个 dic_Point时候将它     
            for ( int n = 0; n <= 100; n++ ) {
                dic_Point.Add ( n.ToString(), n );                if ( n % 5 == 0 ) {
                    Dictionary<string, int> dic_Point_Copy = new Dictionary<string, int> ();
                    dic_Point_Copy = dic_Point;
                    dic_Total.Add ( n.ToString (), dic_Point_Copy );
                    dic_Point_Copy.Clear ();
                    dic_Point.Clear ();
                    
                    GC.SuppressFinalize ( dic_Point_Copy );
                }            }
            Console.Read (); 这样也不行 能提供重新分配地址的方法吗？、

            Dictionary<string, Dictionary<string, int>> dic_Total = new Dictionary<string, Dictionary<string, int>> ();            Dictionary<string, int> dic_Point = new Dictionary<string, int> ();  // 就是 dic_Total装载着dic_Point            // 在循环里面 装载满了一个 dic_Point时候将它     
            for ( int n = 0; n < 100; n++ ) {
                dic_Point.Add ( n.ToString(), n );                if ( n % 5 == 0 ) {
                    Dictionary<string, int> dic_Point_Copy = new Dictionary<string, int> ();  
                    foreach ( KeyValuePair<string, int> key in dic_Point ) {
                        dic_Point_Copy.Add ( key.Key, key.Value );
                    }
                    dic_Total.Add ( n.ToString (), dic_Point_Copy );
                    dic_Point.Clear ();                                  }            }
            Console.Read ();
  尝试了这种 是可以  但是 多了一重循环 我里面很多数据会很慢 ，求解决方法

Answer 3

            Dictionary<string, Dictionary<string, int>> dic_Total = new Dictionary<string, Dictionary<string, int>> ();            Dictionary<string, int> dic_Point=null;// 就是 dic_Total装载着dic_Point            // 在循环里面 装载满了一个 dic_Point时候将它     
              for ( int n = 0; n < 100; n++ ) 
              {
                if(dic_Point==null)
                      dic_Point = new Dictionary<string, int> ();  
                dic_Point.Add ( n.ToString(), n );                if ( n % 5 == 0 ) 
                {
                    dic_Total.Add (n.ToString(), dic_Point );
                    dic_Point = new Dictionary<string, int> ();                  
               }            } 
 

Answer 4

上面的代码还可以精简一点:
            Dictionary<string, Dictionary<string, int>> dic_Total = new Dictionary<string, Dictionary<string, int>> ();            Dictionary<string, int> dic_Point = new Dictionary<string, int> ();  // 就是 dic_Total装载着dic_Point            // 在循环里面 装载满了一个 dic_Point时候将它     
              for ( int n = 0; n < 100; n++ ) 
              { 
                dic_Point.Add ( n.ToString(), n );                if ( n % 5 == 0 ) 
                {
                    dic_Total.Add (n.ToString(), dic_Point );
                    dic_Point = new Dictionary<string, int> ();                  
               }            }
