Prova att använda en nullbar datatyp här för att hålla reda på om Double.TryParse lyckats eller inte. Om man inte gör det påverkas snittet.

Att använda metodaccess direkt följande literaler på detta sättet är något vi anser påverkar läsbarheten i kod.
Vidare så körs operationen PadRight multipla gånger iom att den är placerad i loopen utan att värdet förändras under körning.

Skriv istället:

var label = "Värdet är:";
var paddedLabel = label.PadRight(14);

for (int i = 0; i < inputStringArray.Length; i++)
{
    Console.WriteLine(paddedLabel + inputStringArray[i]);

try
{
double currentNumber = 0;
NumberStyles numberStyles = NumberStyles.Any | NumberStyles.Float; //bitwiseoperator
bool parsed = Double.TryParse(inputStringArray[i], numberStyles, CultureInfo.InvariantCulture, out currentNumber);
if (parsed)
{
numbers[i] = currentNumber;
middlevalue += currentNumber;
}
else continue;

// Debug.Assert(i < numbers.Length - 1);
}
catch (Exception e)
{
Console.WriteLine(e);
throw;
}

}
Console.WriteLine("-------------------------------------------\n");
Console.WriteLine($"Högsta värdet: {numbers.Max()}");//Max value
Console.WriteLine($"Minsta värdet: {numbers.Min()}");//Min value
Console.WriteLine("Medelvärdet för arrayen är: " + string.Format($"{(middlevalue / numbers.Length):0.00}")); //Middle value
