Swapping elements in array using c#

Question

Hello 

 

if  i have an array consist of 5 integers from 1 to 5 like this

int [] numbers={1,2,3,4,5};

So, i want to swap the last number (5) with the first number (1)

And

Swap the second number (2) with the fourth number (4)

 

So the number 3 (which is in the middle will stay in the middle with index of 2).

 

I tried to swap between the first and last number in this manner:

 

numbers[4]=numbers[0];

But i don't know if this is true, and what about the second swapping?
