## ObjectExt::Box(const T\&) method


Boxes value types for converting to [Object](../../object/). Implementation for enum types.

```cpp
template<typename T> static std::enable_if<std::is_enum<T>::value, System::SmartPtr<System::Object>>::type System::ObjectExt::Box(const T &value)
```


| Parameter | Description |
| --- | --- |
| T | [Enum](../../enum/) type. |

| Parameter | Type | Description |
| --- | --- | --- |
| value | const T\& | [Enum](../../enum/) value to box. |

### ReturnValue

Smart pointer to object keeping boxed value.
