# Array.Sort Method (Array)

[ This article is for Windows Phone 8 developers. If youâ€™re developing for Windows 10, see the latest documentation. ]

Sorts the elements in an entire one-dimensional Array using the IComparable implementation of each element of the Array.

**Namespace:** System**Assembly:** mscorlib (in mscorlib.dll)

## Syntax

```
Public Shared Sub Sort ( _
array As Array _
)
```

```
public static void Sort(
Array array
)
```

#### Parameters

- array

Type: System..::.Array

The one-dimensional Array to sort.

## Exceptions

Exception | Condition |
---|---|

ArgumentNullException | array is nullNothingnullptra null reference (Nothing in Visual Basic). |

RankException | array is multidimensional. |

InvalidOperationException | One or more elements in array do not implement the IComparable interface. |

## Remarks

Each element of array must implement the IComparable interface to be capable of comparisons with every other element in array.

If the sort is not successfully completed, the results are undefined.

This method uses the QuickSort algorithm. This implementation performs an unstable sort; that is, if two elements are equal, their order might not be preserved. In contrast, a stable sort preserves the order of elements that are equal.

On average, this method is an O(n log n) operation, where n is the Length of array; in the worst case it is an O(n ^ 2) operation.
