I want to convert int array to int so i can add them.

Example

int[] x = {1, 2, 3};

sum=x[0]   x[1]   x[2];

I have a loop for getting an input from user but i have to add all the values of every inputted.

Use the .Sum LINQ method:

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

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

CodePudding user response：

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).
