What's the difference between i-- and --i in c#

Question

How does "i--" differ from "--i" in c#? is this the same? it seems to equate to the same thing.

i--;

other answers seem to say i++ or ++i, but i am asking about i-- or --i

google `predecrement` and `postdecrement` operators. https://www.google.com/webhp?q=pre%20decrement%20and%20post%20decrement%20in%20c%23 — Alex, Oct 29 '14 at 19:18
@YourMomma Google can be a generic term in common discussions. It means "go use a search engine". It doesn't have to mean use google.com. Bing will work just fine. — mason, Oct 29 '14 at 19:20

--i decrements the variable i BEFORE an operation, i-- after. makes a big difference in, for example,

int i=5;
Console.WriteLine(--i);

i=5;
Console.WriteLine(i--);

Your example produces the exact same output whether you use `i++` or `++i` in the loop. – D Stanley Oct 29 '14 at 19:31
