saving values from a multi-dimensional array

August 1st, 2017, 09:16 AM

Hi i need too saving some values in a multi-dimensional array
i have done it i a singel array like this
Upp1 = CUpp[1];
Upp2 = CUpp[2];
Upp3 = CUpp[3];
Upp4 = CUpp[4];
Upp5 = CUpp[5];
CuppSum = Summationarray(CUpp,5);
but i cant find the solution for multi-dimensional.
Thanks Infe

infe2015,

what exactly seems to be the problem?

When storing values in a multidimensional array the only difference is that you have to specify all dimensions.

For your summation you will likely have to build your own function/code that cycles through all the array elements that you want to sum using a for loop.

You can certainly achieve this using a recursive method.

BE AWARE, RECURSION CAN BE VERY SLOW AND MEMORY INTENSIVE!

Here is some C# code where I create an array with the following elements:
Element 0: Value 1
Element 1: Array with values 2 and 3
Element 2: Value 4
Element 3: Array with 2 elements:
Element 0: Array with two values: 5 and 6
Element 1: Value 7

The sum should be 28.

static void Main(string[] args)
{
object[] o = new object[4];
int value1 = 1;
object[] array1 = new object[2] {2, 3};
int value2 = 4;

object[] array_2_element_0 = new object[]{5,6};
object[] array2 = new object[2]{array_2_element_0, 7};

o[0] = value1;
o[1] = array1;
o[2] = value2;
o[3] = array2;

int sum = Sum(o);
Console.WriteLine(sum);
}

private static int Sum(object obj)
{
int result = 0;

if (obj is object[])
{
object[] arr = (object[]) obj;
foreach (object o in arr)
{
result += Sum(o);
}
}
if (obj is int)
{
result = (int) obj;
}

return result;
}

Also, it just occurred to me, that you might be asking how to access array elements beyond the first dimension. It is done like this:

int x = array[0][0];

However, if you don't know how many dimensions you will have, then you must iterate through every element, rather than access elements by index.
