How can i Order By Descending this array?

Answer 1

You can use Array.Sort by passing a comparison function.

using namespace System;

int Compare(String^ a, String^ b)
{
    return String::Compare(a, b, StringComparison::OrdinalIgnoreCase) * -1;
}

auto ar = gcnew cli::array<String^>{ "3", "1", "4", "5", "2" };
Array::Sort(ar, gcnew Comparison<String^>(Compare));

Alternately, you can sort with an ascending order and reverse the array.

Array::Sort(ar, StringComparer::OrdinalIgnoreCase);
Array::Reverse(ar);
