Determine if array contains all zeroes

Question

I create the following array like this:

array<UInt16>^ temp = gcnew array<UInt16>(1000);

How do I determine if this entire array has been filled with zero or not.

I think I may be able to use TrueForAll(T) but I'm not sure.

Answer 1

This should work properly (here I used LINQ):

IEnumerable<int> values = new List<int>(); // Or use any array type instead of List.

... Add your values here ...

var allAreZero = !values.Any(v => v != 0);

P.S. the array class inherits IEnumerable.

And here is a solution with foreach:

var isAllZero = true;
foreach (var value in values)
{
    if (value != 0)
    {
        isAllZero = false;
        break;
    }
}

UPDATE

The really difference between TrueForAll, and my LINQ code is: LINQ code uses the fluent (or maybe also query) syntax, where TrueForAll is just a normal function where you send the array as a parameter.
