Boxing and Unboxing

Question

I have a small doubt regarding Boxing and Unboxing in C#. ``` int i=1; System.Int32 j = i; ``` above code can be called as boxing?

Accepted Answer

No, that's not boxing at all. `int` is just an alias for `System.Int32`. That code is equivalent to:

```
int i = 1;
int j = i;
```

For boxing to occur, there has to be a conversion to a reference type, e.g.

```
int i = 1;
object j = i;
```

Or:

```
int i = 1;
IComparable j = i;
```
