c# - 分别打印字典的键和值

Question

我有一个包含键和值的字典.我想打印到控制台的键和值.但我想分别打印键和值.y是唯一的,m是分配给键的值.

看到我在这里尝试如何做到这一点,但我得到一个错误说

预期方法,代表或事件

码:

List<int> col = new List<int>();
Dictionary<int, int> dic = new Dictionary<int, int>();
//iterates through min-max
for (int y = 0; y <= 15; y++)
   {   
 int m = 0;
   //iterates through array
      for (int i = 0; i < Arr.Length; i++)
         { 
            //comparisons
              if (y == Arr[i])
              {
                 m++;

               }

           }
 dic.Add(y,m);  
 Console.WriteLine("Number {0} appears {1} times ", y, dic[y]);

您可以使用索引器dic[something]操作来获取给定键的值.

Dictionary<int, int> dic = new Dictionary<int, int>();
//rest of my code here
{...}
dic.Add(y,m);
Console.WriteLine("Number {0} appears {1} times ", y, dic[y]);
