## Array::BinarySearch(System::ArrayPtr\<T\>, const T\&) method


Выполняет бинарный поиск в отсортированном массиве.

```cpp
static int System::Array<T>::BinarySearch(System::ArrayPtr<T> arr, const T &item)
```


| Параметр | Тип | Описание |
| --- | --- | --- |
| arr | System::ArrayPtr\<T\> | Отсортированный массив для выполнения поиска |
| элемент | const T\& | Элемент для поиска |

### ReturnValue

[Index](../../index/) of the searched item if one is found, otherwise, a negative integer that is the bitwise complement of the index of the next item greater than searched item or, if there is no greater item, the bitwise complement of the number of elements in the array.
