// получаем строку с элементами
string Str1 = listBox1.SelectedItem.ToString();
// разделяем строку в массив строк по символу "пробел"
var strings = Str1.Split(' ');
// Преобразуем все строки в числа
var items = strings.Select(double.Parse);
// Находим максимальный элемент
var max = items.Max();
// Ищем индекс максимального элемента
var maxIndex = Array.IndexOf(items, max);

// Можно сократить запись:
string Str = listBox1.SelectedItem.ToString();
var items = Str.Split(' ').Select(double.Parse).ToArray();
var maxIndex = Array.IndexOf(items, items.Max());
