✅ List gets weird numbers

string example = "9d4f1";
List<int> ints = new List<int>();

foreach (char c in example)
{
    if (Char.IsDigit(c))
    {
        if (ints.Count != 2) ints.Add(c);
        else ints[1] = c;
    }
}

foreach (var item in ints) Console.WriteLine(item);

string example = "9d4f1";
List<int> ints = new List<int>();

foreach (char c in example)
{
    if (Char.IsDigit(c))
    {
        if (ints.Count != 2) ints.Add(c);
        else ints[1] = c;
    }
}

foreach (var item in ints) Console.WriteLine(item);

I was hoping for this to take the first int and the last int, yes there are probably better ways to do this but I am new to c# and want to come up with my own solutions.

Atm if I run this code then "ints[0]" comes out as 57 (should be 9)
and "ints[1]" comes out as 49 (should be 1)

my idea was that it first uses the Add function to add 2 indexes (0 = the first number)
then if it found more numbers then 2 if would just replace the last index (1).

If anyone know why the values come out as they do, any help would be much appreciated
