Example

[Visual Basic, C#, C++] The following example shows how to sort two associated arrays where the first array contains the keys and the second array contains the values. Sorts are done using the default comparer and a custom comparer that reverses the sort order. Note that the result might vary depending on the current CultureInfo.

[Visual Basic, C#, C++] Note   This example shows how to use one of the overloaded versions of Sort. For other examples that might be available, see the individual overload topics.
