How to Sort Two Arrays with Array.Sort in .NET

The method Array.Sort(array, array) has been available since .NET Framework 2.0, but I recently discovered it. It allows sorting a pair of arrays, with the first array used as keys and the second as values:

var keys = ['A','C','B'];
var values = [1,3,2];

Array.Sort(keys, values);

// keys = ['A','B','C']
// values = [1,2,3]

The result is that both arrays are sorted, preserving the relationship between keys and values. Additionally, you can provide a custom Comparer to define your own sorting logic.

While Array.Sort is not commonly seen in "commercial" code nowadays, I found this feature quite interesting and versatile!
