You can do this in a number of ways.

first by making a loop yourself.

static int Sum(int[] array)
        {
            int sum = 0;
            foreach (var item in array)
            {
                sum += item;
            }
            return sum;
        }
        static void Main()
        {
            int[] x = new int[] { 1, 2, 3 };
            Console.Write(Sum(x).ToString());
        }

second, using the Sum() method in the System.Linq library

using System.Linq;

////
int[] x = new int[] { 1, 2, 3 };
Console.Write(x.Sum());

thank you USEFUL for feedback if it worked for you

It is not really clear what the problem is. Your code seems fully functional, so it is difficult to know what you are really trying to achieve and what the underlying issue it.

But certainly a simple loop would work fine.

int sum = 0;
for(int loop=0; loop < x.Length; loop++)
{
    sum += x[loop];
}

You can also do this via Linq (I see somebody else posted that example, so I won't repeat it).

Use the .Sum LINQ method:

var x = new int[] { 1, 2, 3 };
var sum = x.Sum(); // gives 6
