Finding the sum of an array?

If I have an array of integers, how can I automatically find the sum of the array?

Iteratively sum the elements, like this:

public int SumArray(int[] toBeSummed)
{
    int sum = 0;

    foreach (int item in toBeSummed)
    {
        sum += item;
    }

    return sum;
}

Something like this:

var ints : int[];
var total : int;


function Awake () {
    for(var i = 0; i<ints.length; i++){
        total += ints*;*

}
}
