C# dynamically access variables based on user input

Question

I am new to C# but have school project that i am working on and need some guidance. I have multiple arrays which i termed array1, array2, array3 , array4 and so on till array9. Now the user is entering digits into input box and i am splitting the input like 543 into 5 4 3 and i want to dynamically call

array5 array4 array3. So basically show contents of these arrays in console.

string value = input.Text.ToString();

 foreach (string s in Array[value[0]])
    {
    -- will loop through all values of array and out put
    foreach (string s in Array[value[1]])
      {
       -- will loop through all values of array and out put
          foreach (string s in Array[value[2]])
          {
          -- will loop through all values of array and out put
          }
       }
    }

How do i accomplish this ? Please help

Why are there 9 array variables? The entire point of collections is to eliminate multiplicity from variables. — user2864740

I don't understand either. Are you trying to make an array for each number? — Kaj

Do array or arrays: array[9][n], now you can access to X array, for example array[4][2] = ... — AsfK

@user2864740 Yes those are just array names i used for example. So array will have different items in them like collections which will get selected once user enters the desired numbers. — Manny Balboa

Try

var arrays = new List<int[]>(){array1,....,array9};

and then if you have 5, 4, 3 you can call arrays like

arrays[4], arrays[3], arrays[2]

I did that but it says var the type or namespace cannot be found c#

then read more about what is var ... you have another mistake, I assume you have problem with brackets

This is what i typed var arrays = new List<int[]>{Array2,Array3,Array4,Array5,Array6,Array7,Array8,Array9};

important is, where you typed this code. Are you inside of method or constructor? Probably not. Code more, ask less ;)

Here's my code. Its just frustrating :( 'string[] Array2 = new string[3] { "A", "B", "C" }; string[] Array3 = new string[3] { "D", "E", "F" }; string[] Array5 = new string[3] { "J", "K", "L" }; string[] Array6 = new string[3] { "M", "N", "O" }; string[] Array7 = new string[3] { "P", "R", "S" }; string[] Array8 = new string[3] { "T", "U", "V" }; string[] Array9 = new string[3] { "W", "X", "Y" }; List<int[]> data = new List<int[]> { Array2, Array3, Array4, Array5, Array6, Array7, Array8, Array9 };'
