Index of Array List

[fsl88]

Hello everyone. Need help on getting the index number of the minimum value, and the index number of the 2nd minimum value.

Pictured below gets the actual value of the minimum and 2nd minimum value respectively.

This is in a (for loop).

Thank you.

Hi,

It is very difficult (if not impossible) to answer you without knowing what arrayLength, skip1, take1 are. You should provide some example of these collections.

Here's an extension method which sorts the elements in a collection, and returns the element index numbers.

public static IEnumerable<int> SortI<T>(this IEnumerable<T> source) where T : IComparable
{
    int i = 0;
    return source
        .Select(x => new { Value = x, Index = i++ })
        .OrderBy(x => x.Value)
        .Select(x => x.Index);
}

> var array = new[] { 1, 3, 5, 2, 4, 6};
> array.SortI().ToArray()
int[6] { 0, 3, 1, 4, 2, 5 }
