You need to cast it to its original type

string item1 = (string) array_list[0];
int item2 = (int) array_list[1];
double item3 = (double) array_list[2]

Answer 2

namespace Sololearn
{
class account{
public static int[] a={"hi",111,4.5};
}
class Program
{
static void Main(string[] args)
{
int x=0;
Double V;
V=account.a[x+2];

}
}
}

You might want to store the elements in a non-generic collection, such as ArrayList, object[], or List<object>, the first one is not recommended though due to performance issue

Hope this helps 👍

Calm down, it's just a question

Answer 5

Ever considered using a Struct or a Class? Then you can store the class objects in an array or a list later on

Why enum?

Answer 7

It's simpler. And you can put ANY of variables

Answer 8

And don't call it like only int[] or List<int>()

Answer 9

Class

Answer 10

What is the other way to get a value from an array?

Answer 11

As I understand it, we cannot mix various types of values in array. So { "hi", 111, 4.5 } itself may require extra work/research to accomplish.

Answer 12

Just make enumerator, and then you can put variables, and set elements directly or in declaring.
enum a ={Integer=111,str = "Hi", Doublev = 4.5};
