Array.Sort Method (Array, Int32, Int32)
July 28, 2014
Assembly: mscorlib (in mscorlib.dll)
array is null.
array is multidimensional.
index is less than the lower bound of array.
length is less than zero.
index and length do not specify a valid range in array.
One or more elements in array do not implement the IComparable interface.
Each element within the specified range of elements in 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 length; in the worst case it is an O(n ^ 2) operation.
