## IOrderedEnumerable::LINQ_ThenBy(const Func\<T, Key\>\&) method


Performs a subsequent ordering of the elements in a sequence in ascending order according to a key.

```cpp
template<typename Key> SharedPtr<IOrderedEnumerable<T>> System::Linq::IOrderedEnumerable<T>::LINQ_ThenBy(const Func<T, Key> &keySelector)
```


| Parameter | Description |
| --- | --- |
| Key | The type of the key returned by keySelector. |

| Parameter | Type | Description |
| --- | --- | --- |
| keySelector | const Func\<T, Key\>\& | A function to extract a key from each element. |

### ReturnValue

[System::Linq::IOrderedEnumerable](../) whose elements are sorted according to a key.
