c# Array.FindAllIndexOf which FindAll IndexOf

Question

I know c# has Array.FindAll and Array.IndexOf.

Is there a Array.FindAllIndexOf which returns int[]?

Answer 1

You can solve this problem by creating only 2 integer variables. More power to you!

string[] seasons= { "Fall","Spring", "Summer", "Fall", "Fall", "Winter"};

int i = 0;

int IndexOfFallInArray = 0;

int[] IndexesOfFall= new int[seasons.Length];

foreach (var item in seasons)
{
    if (item == "Fall")
        {
            IndexesOfFall[i] = IndexOfFallInArray;
            i++;
        }
        IndexOfFallInArray++;
}
