Question

I have an array of booleans which gets filled by a loop. The method that owns the array needs to return a single boolean. So can I do this:

bool[] Booleans = new bool[4];

// do work - fill array

return (Booleans[0] && Booleans[1] && Booleans[2] && Booleans[3]);

So if I have: T,T,F,T will I get F back since there is one in the array or will it send back something else or just crash all together?

Answer 1

A single false will result in false being returned with boolean AND logic.

You can also rewrite as:

return Booleans.All(b => b);

For the sake of completeness, or if LINQ is not an option, you can achieve the same via a loop:

var list = new List<bool> { true, false, true };

bool result = true;
foreach (var item in list)
{
    result &= item;
    if (!item)
        break;
}

Console.WriteLine(result);

For small samples what you have is fine, but as the number of items grow either of the above approaches will make the code a lot friendlier.
