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)

static member Sort : 
        array:Array -> unit

Parameters

array
Type: System.Array

The one-dimensional Array to sort.

Exception Condition
ArgumentNullException

array is null.

RankException

array is multidimensional.

InvalidOperationException

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

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 introspective sort (introsort) algorithm as follows:

  • If the partition size is fewer than 16 elements, it uses aninsertion sort algorithm.

  • If the number of partitions exceeds 2 * LogN, where N is the range of the input array, it uses a Heapsort algorithm.

  • Otherwise, it uses a 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.

For arrays that are sorted by using the Heapsort and Quicksort algorithms, in the worst case, this method is an O(n log n) operation, where n is the Length of array.

The following code example shows how to sort the values in an Array using the default comparer and a custom comparer that reverses the sort order. Note that the result might vary depending on the current CultureInfo.
