# What is Boxing and Unboxing in C#

**Boxing :****\****Boxing** is the process of converting a *value type* to the *object* *type*.When the CLR boxes a value type, it wraps the value inside a System.Object and stores it on the managed heap.\
**Example** :\

```
int i = 123;    // The following line indicates the boxing of i.object o = i;
```

**Unboxing :**\
**Unboxing** is an explicit conversion from the type *object* to a *value type*\

```
 o = 123;// The following line indicates the unboxing of o. i = (int)o;
```
