Description Kirill 2013-09-11 03:21:59 UTC
Hello! I found difference in behavior of function Array.FindLastIndex

.Net code looking for item from startIndex to 0
mono code looking for item from last index to startIndex

Please provide a test case that shows this behavior difference.

Why does it even matter as it looks like mono is doing the right thing.
Comment 2 Kirill 2013-09-13 03:32:32 UTC
test code:

public static void TestFindLastIndex() {
    int[] ii = new int[] {1, 0, 0};
    int r = Array.FindLastIndex(ii, 1, x => x != 0);
    Console.WriteLine("index: {0}", r);
}

public static void Main(string[] args) {
    TestFindLastIndex();
}

mono: index: -1
.net: index: 0
