c＃如何将数组更改为数组或数组

Question

我有这个代码：

int[] ivrArray = { 1, 0, 0, 0};
int[] agentsArray = { 0, 2, 0, 0 };
int[] abandonedArray = { 0, 0, 3, 0};
int[] canceledArray = { 0, 0, 0, 4};
Dictionary<string, int[]> dictionary = new Dictionary<string, int[]>()
            {
                { "IVR", ivrArray },
                { "Agents", agentsArray },
                { "Abandoned", abandonedArray },
                { "Cancelled", canceledArray },    
            };

输出是

{
  "IVR": [
    1,
    0,
    0,
    0
  ],
  "Agents": [
    0,
    2,
    0,
    0
  ],
  "Abandoned": [
    0,
    0,
    3,
    0
  ],
  "Cancelled": [
    0,
    0,
    0,
    4
  ]
}

无论如何，输出将是这样的：

"Cancelled":[
   [0],
   [0],
   [0],
   [4]
]

所以每个元素都是一个元素的数组

Answer 1

您可以将数组重新投影到Dictionary<string, int[][]>如下所示：

 var dictionary = new Dictionary<string, int[][]>
    {
       {"IVR", ivrArray.Select(_ => new[] {_}).ToArray()},
       {"Agents", agentsArray.Select(_ => new[] {_}).ToArray()},
       {"Abandoned", abandonedArray.Select(_ => new[] {_}).ToArray()},
       { "Cancelled",canceledArray.Select(_ => new[] {_}).ToArray()}
    };

（我想如果你不想要当地的变种那么

 ...
   {"IVR", new [] { 1, 0, 0, 0 }.Select(_ => new[] {_}).ToArray()},
 ...

你可以使用Jagged Arrays概念做到这一点：

例如：

int[] list1 = new int[4] { 1, 2, 3, 4};
int[] list2 = new int[4] { 5, 6, 7, 8};
int[] list3 = new int[4] { 1, 3, 2, 1 };
int[] list4 = new int[4] { 5, 4, 3, 2 };

int[][] lists = new int[][] {  list1 ,  list2 ,  list3 ,  list4  };

在字典中：

 Dictionary<string, int[][]> items= new Dictionary<string, int[][]>;
