Array.Sort Method (Array)

Microsoft Silverlight will reach end of support after October 2021. Learn more.

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

'Declaration
Public Shared Sub Sort ( _
    array As Array _
)

public static void Sort(
    Array array
)

Parameters

Exceptions

Exception Condition
ArgumentNullException

array is nulla 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.
