What is the easiest way to reverse an array in C#, without using Array.Reverse? [duplicate]

Question

I tried this and the output is 5 4 3 4 5 instead of 5 4 3 2 1.

for (int i = 0; i < numbers.Length;i=i+1)
        {
            int tmp = numbers[i];
            numbers[i] = numbers[numbers.Length - i - 1 ];
            numbers[numbers.Length - i - 1 ] = tmp;
            Console.WriteLine(numbers[i]);

you can use stack.

My first question would be why not just use Array.Reverse. But in any case, your bug is in the exit condition of your for loop. You need to stop at numbers.Length/2 or you just swap everything back.
