c# how to change array to array or arrays

Question

I have this code:

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 },    
            };

The output is

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

Is there anyway so the output will be like this:

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

So each element is array of one element

@AvnerShahar-Kashtan that is a library that changes that c# object to json. it does't matter what the object is. It can change any object to json object. it is json.net library. but my question is how to make that c# object contains array of arrays , not just arrays. got me ? — Marco Dinatsoli

Are you asking how to rewrite the code so that it creates a set of int[][] instead of int[], or asking how to write code which converts the given int[] to int[][]? — Avner Shahar-Kashtan

@AvnerShahar-Kashtan the first one, hot to change int[] to int[][],i tried myself to do like this: int[][] ivrArray = { [1], [0], [0], [0]}; but I got syntax error — Marco Dinatsoli

You can re-project your arrays to a Dictionary<string, int[][]> like so:

 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()}
    };

(and I guess if you didn't want the local vars, then

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

can i say Dictionary<string, int[][]> dictionary instead or var dictionary ?

StuartLC Over a year ago

@MarcoDinatsoli Y, sure, although the var variable is still strongly and correctly typed to Dictionary<string, int[][]> :)

you can do like this using Jagged Arrays concept:

for example:

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  };

and in dictionary:

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

here is MSDN documentation:
