Difference between int and new int()

Question

I didn't understand the actual use of new int()

So my qustion is what is the difference between

int myNumber = 5;

and

int myNumber = new int();

What is the best use of new int() or when should we use new int() I know the memory allocation difference (stack and heap) but i didn't find any actual use of new int()

"I know the memory allocation difference (stack and heap)" Do you? See [here](http://blogs.msdn.com/b/ericlippert/archive/2009/04/27/the-stack-is-an-implementation-detail.aspx) :) — DaveShaw, Jul 09 '13 at 09:40

Never use new int();. Always use:

int myNumber = 5;

There is no difference between the two of them. But you should never instintiate your value types with the 'new' keyword.

bool myBool = new bool(); // <== just looks odd, right?

I just want to ask, why? – Soner Gönül Jul 09 '13 at 09:40
Even if there is a difference, as pointed out by others. The difference is so tiny you should not bother about 4 Bytes (an integer), except if you're programming for micro processors. Instead you should bother about readability of your written code. – Fabian Bigler Jul 09 '13 at 09:45
There are times, especially in generic programming, where you might well be doing a `new int()` under the hood. – Moo-Juice Jul 09 '13 at 09:49

int myNumber = new int();

is equivalent to:

int myNumber = 0;

int myNumber;

int myNumber = 0;

int myNumber = new int();

The effect should be exactly the same, you can try to ILDASM them if you're doubtful
