	Array keys,
	Array items,

Parameters

keys
Type: SystemArray
The one-dimensional Array that contains the keys to sort.
items
Type: SystemArray
The one-dimensional Array that contains the items that correspond to each of the keys in the keysArray.-or-null to sort only the keysArray.
index
Type: SystemInt32
The starting index of the range to sort.
length
Type: SystemInt32
The number of elements in the range to sort.
comparer
Type: System.CollectionsIComparer
The IComparer implementation to use when comparing elements.-or-null to use the IComparable implementation of each element.
Exceptions
ExceptionCondition
ArgumentNullExceptionkeys is null.
RankExceptionThe keysArray is multidimensional.-or-The itemsArray is multidimensional.
ArgumentOutOfRangeExceptionindex is less than the lower bound of keys.-or-length is less than zero.
ArgumentExceptionitems is not null, and the lower bound of keys does not match the lower bound of items.-or-items is not null, and the length of keys is greater than the length of items.-or-index and length do not specify a valid range in the keysArray.-or-items is not null, and index and length do not specify a valid range in the itemsArray. -or-The implementation of comparer caused an error during the sort. For example, comparer might not return 0 when comparing an item with itself.
InvalidOperationExceptioncomparer is null, and one or more elements in the keysArray do not implement the IComparable interface.
